So you got the iPhone 4S or just update your older iPhone to iOS 5, now its time to really learn how to really use it.

Much like OS X Lion this past summer, iOS 5 has far more new features than Apple’s Marketing team would lead you to believe. You’ve probably discovered key features like Notification Center. iMessage, Newsstand, and Reminders on your own, but have you taken the time dig deeper in Search of other Seemingly hidden gems?

1. Accessibility: Custom Vibration (iPhone)

Thanks to Improvements with IOS 5’s accessibility features, iPhone users can now choose custom vibrations to alert them to incoming notifications. Head in Settings > General > Accessibility and switch on “custom Vibrations” under the Hearing section, Now you’ll see a new “Vibration Patterns” section in the sounds settings panel where you can select frorn several defaults or create your own. These can even be assigned to specific contacs by tapping Edit and making your selection under the Ringtone field.

 2. Accessibility: Led Flash Alerts (iPhone)

If You’d rather see in abet rather than feel it, jump bath to setings > General >  Accessibility and turn on “LED Flash for Alert.” Now, incoming calls and other alerts will flash the LED light on the back of your iPhone – and maybe let you relive the 70’s disco era, if you let the flash go on long enough.

3. App Store: Multiple App Downloads

In another one of those little conveniences that will make life with i0s 5 easier, the App Store now allows for multiple apps to download al the some Time-no more waiting for one to finish before the next one gets started.

4. App Store: Purchase History

With iOS 5, you can easily find forgotten  apps and download them again. On the iPhone or iPod touch, head to App Store > Updates and tap ‘Purchased’ to see a list of all purchase or only the ones. Not on this iDevice (iPad users have a dedicated Purchased tab). Tap the little cloud symbol next to the app in question to re-download it.

5. Bluetooth: Stream Song Details

Those of us with Bluetooth-enabled car stereos will definitely appreciate this one: iOS 5 now allows track, artist and album names to stream over Bluetooth. Now let’s get on that album artwork and we’ll all be happy.

6. Calendar: Drag To Adjust

Tip and hold an existing event in iOS 5 and then drag it to adjust either the time or duration. Yeah, we know… we just blew your mind, right?

7. Calendar: Edit Calendars

At long last, iOS 5 allows you to add, rename or even delete calendars! From the Calendar app, tap the “Calendar” button at upper left, then Edit and make your changes. New calendars can be added by taping “Add Calendar” at the bottom; exiting calendars can be given a new color by tapping on them and making a selection. to delete a calendar, tap the “Delete Calendar” button while editing a particular one.

8. Calendar: Page Turns (iPad)

Taking a nod from the OS X Lion version of iCal, the iPad Calendar app now has a pleasing page turn animation as you swipe through your busy schedule.

9. Calendar: Press And Hold For New Event

Tapping the “+” symbol to add a new event is s0 iOS 4. That’s because iOS 5 now allows you to simply tap on a day, hold your finger in place for a moment and up pops a new event, ready to accept your details.

1o. Calendar: Swipe To Change Days

Apple has implemented the ability to swipe between days in iOS 5 instead of having to tap those tiny arrows. Nice!

11. Calendar: Time Zone Support

Adding a new calendar event that takes place in another time zone? No more mind-bending mental gymnastics, iOS 5 now presents a new Time Zone option when adding an event. Simply tap to enter your start and end day/time as usual, tap “Time Zone” and enter the name of the city or region you’ll be visiting when the event occurs. Now enter the event in that city’s local time and get on with your day.

12. Calendar: Weekly View (iPhone/iPod touch)

Turn your device to landscape mode and a new Weekly view magically appears before eyes. Scroll left or right with your finger to get a look at what’s come before and what’s coming up, respectively.

13. Calendar: Year View (iPad)

There’s a treat in store for tablet users with the new Year view. Simply tap the icon and you’ll see the same kind of annual “heat map” view OS X Lion users also now enjoy, with busier days shown in “hotter” colors.

14. Camera: Gride Lines (iPhone/iPod touch)

From the Camera app, tap Options and then switch on “Grid” to bring up handy lines you can use to compose your shot using the rule of thirds or other methods the pros would approve of.

15. Camera: Pinch To Zoom (iPhone)

While shooting a photo in the Camera app, simply use the now-familiar two-finger pinch to zoom into (or out of) your shot. For those who prefer the old style, the classic zoom slider will pop up once you initiate a pinch to zoom.

16. Camera: Quick Access (iPhone)

One of our favorite new features in iOS 5 is the ability to double-click on the Home button while the iPhone is locked, which then displays a small camera icon in the lower right corner next to the familiar “Slide to Unlock” option. Tap the camera icon and without further ado, you’re immediately transported into the Camera app. Users will only have access to the photos being taken during that session–the rest of the device remains locked out.

17. Camera: Return To Camera

While viewing your photos or vide in the Camera app, you can now jump right back into shooting by tapping the blue camera icon in the lower right corner.

18. Camera: Shutter Button (iPhone)

The third-party Camera+ app once had a secret feature that used the volume up button as a camera shutter when taking pictures, and Apple must have been paying attention, because it’s now standard with iOS 5 at least for the built-in Camera app.

19. Facetime: 3G Where Supported

Apple hasn’t said much about it, but iOS 5 now allows FaceTime calls over 3G as well as Wi-Fi. The catch? Your carrier has to support the feature, which means it’s useless for those of us in the United States, since none of the three carriers here currently support it.

20. Game Center: Profile Picture

Gamers will now have a visual identity to go along with their handle, thanks to iOS 5 allowing a photo to be uploaded and shared with your friends. Simply tap the photo icon next to your Game Center handle, choose your best look (and crop it, if so desired) and you’re good to go.

21. Game Center: Friend Recommendations

Apple has also made it easier to find your friends in Game Center with iOS 5, thanks to the ability to upload your address book and offer recommendations based on who’s already hanging out there.

22. Game Center: Game Recommendations

If you play a lot of games and are always seeking recommendations for new ones, the Game Center app now includes a section dedicated to Apple’s own suggestions, which will open right up in the App Store with just a tap.

23. iCloud: Automatic Downloads

Want to make sure your next iTunes music, App Store or iBookstore purchase goes straight to all of your devices without having to think about it? Head to Settings > Store and toggle on the appropriate switches under Automatic Downloads. iPhone and 3G iPad users also have the option to “Use Cellular Data,” which users on metered data plans might want to toggle off before flipping the switch on this feature.

24. iCloud: Backup

Apple includes 5GB of free storage with each iCloud account, which is plenty for most of us to backup our device (or two). But you’ll need to set it up first! Head to Settings > iCloud > Storage & Backup and make sure “iCloud Backup” is toggled on. Anytime you’re plugged in, locked and on a Wi-Fi connection, the device will back up your precious Camera Roll, accounts, documents and settings without having to think about it.

25. iCloud: Application Data Backup

If that 5GB of free iCloud storage is getting tight, you can manage what gets backed up by heading to Settings > iCloud > Storage & Backup. Tap “Manage Storage” where you can view backups for other devices (and even delete them) as well as see a list of Backup Options for your current device, where users can turn off cloud-based backups for known storage hogs like the Camera Roll.

26. iCloud: Photo Stream

After signing up for your free 5GB iCloud account, make sure you’re making the most of it by turning on Photo Stream. From your iOS 5 device, head to Settings > Photos and flip on the Photo Stream switch. Newly taken photos will get uploaded to iCloud over Wi-Fi, where they’ll be available from all of your devices using Photo Stream.

27. iTunes Store: Tones

The iTunes Store now features a nifty Tones Store which can be accessed from General > Settings > Sounds with the “Buy More Tones” button found under any of the sound settings there. 99 cents per tone might sound expensive, but officially licensed stuff from Star Wars or even Al Pacino’s famous “Say hello to my little friend!” from Scarface is priceless.

28. Keyboard: EMOJI

Jump to Settings > General > Keyboard, tap “International Keyboards” then “Add New Keyboard” and select Emoji. Tap on the globe next to the Space bar to switch to Emoji and get your emoticons on.

29. Keyboard: International Keyboard Shortcut

If you speak several languages, tapping on the globe icon to switch between them can be kind of a drag. Make life easier by holding your finger down on the globe icon and tapping to select the language you want.

30. Keyboard: Shortcuts

If you’re a fan of TextExpander on the Mac, you’ll love iOS 5′s new system wide keyboard shortcuts. Found under Settings > General > Keyboard, users can now tap “Add New Shortcut” to enter frequently used words, addresses and more which can be called up via the shortcut of your choice. Type your shortcut from most anywhere, hit the Space bar, and watch as your selection gets pasted in.

31. Keyboard: Split Keyboard (iPad)

Apple has added the ability to split the iPad’s keyboard in half. Use two fingers to swipe across the keyboard toward the edges and it breaks apart for easier typing. Slide it back together by going in the opposite direction.

32. Keyboard: Turn Off Split Keyboard (iPad)

If you want to make sure you never to accidentally call up the split keyboard ever again, head to Settings > General > Keyboard and toggle “Split Keyboard” off.

33. Keyboard: Twitter

Built-in Twitter integration is one of the star features of iOS 5, but maybe you didn’t notice those convenient little @ and # keys on the keyboard when you’re preparing a new tweet? Rather handy, we think…

34. Mail: Rearrange Addresses

Thanks to iOS 5′s newfound ability you can tap on a recipient and drag them to another field. Move your To: recipient to the CC: or BCC: fields or vice versa… you’re in charge, buddy.

35. Mail: Edit IMAP Mailboxes

By now, most of us are using IMAP for email since it keeps emails on the server and available from multiple devices. That’s good news for iOS 5 users, who now have the ability to add, edit and delete existing IMAP-based mailboxes, including renaming them right from the device.

36. Mail: Hotmail

This one kind of quietly slipped under the radar, but iOS 5 (as well as OS X Lion) now allow Hotmail users to join in the fun, no hackery required. Head to Settings > Mail, Contacts, Calendars and tap “Add Account”. Just like magic, near the bottom of the list you’ll see Windows Live Hotmail as a new option.

37. Mail: Improved Search

Not only does iOS 5′s Mail app allow you to search through an entire mail message, you can now continue your search onto the mail server itself.

38. Mail: Rich Text Formatting

If you need to get your email message across with words in bold, italic or underline, you’ll love the way iOS 5 now allows for rich text formatting while composing new emails or replying to existing ones. Select the text as you would for copy and paste, tap the sideways triangle and you’ll now see an option for “MU” — tap it and up pops the ability to apply bold, italic or underline to the selected text.

39. Mail: S/Mime Support

We all want to keep our email as secure as possible, which is why Apple has now added S/MIME support to the Mail app. An acronym for Secure/ Multipurpose Internet Mail Extensions, S/MIME can be switched on for accounts which support it by going to Settings > Mail, Contacts, Calendar, selecting the account, tapping “Advanced” and toggling S/ MIME on.

40. Mail: Swipe For Messages (iPad)

While reading an email on iPad, swipe your finger from left to right to pull out the list of messages, then swipe from right to left to tuck it away once more.

41. Mail: 1,000 Downloads Maximum

If you frequently find yourself searching through virtual piles of email in the Mail app, you’ll appreciate iOS 5′s ability to download up to1,000 emails, up from the previously paltry limit of only 200.

42. Maps: Alternate Routes

Searching for directions using iOS 5 Maps app will now offer more than one route, should another exist. Most of our searches come up with a minimum of three suggested routes, and tapping on each shows the difference in time and mileage.

43. Messages: New Bubble Colors (iPhone)

iMessage users will show a blue Send button, with the word “iMessage”

44. Messages: Read Receipts

IOS 5 has a new super-powered Messages app with the ability to send messages to other iOS 5 device users without SMS charges. Even better, you can see confirmation that your iMessage has been received thanks to the new “Send Read Receipts” toggle switch. Head to Settings > Messages to flip it on.

45. Messages: Send As SMS

This one is for iPhone users only: If you’re heading out into the great unknown without WiFi, head to Settings > Messages and flip on the “Send As SMS” switch. Now you’ll still be able to fire off witty missives to friends and family using your carrier’s SMS—and if you have one of those swanky unlimited text messaging plans, it still won’t cost you a dime (more).

46. Messages: Group Messaging

Have a message that’s so great you want to broadcast it to everyone you know? Show Subject Field iOS 5 now allows for group messaging, head to Settings > Messages and toggle on “Group Messaging” in the SMS/MMS section at the bottom of the screen. You can start typing a name to select it as usual, or tap the + symbol to choose from your address book, one at a time.

47. Music: Delete Tracks

The new iOS 5 Music app now allows you to swipe over unwanted tracks and delete them if space is at a premium or, you know, enough is enough with novelty songs like Ray Stevens’”The Streak” already.

48. Music: Edit Playlists

Another welcome change in the new Music app is the ability to tap New to create playlists on the go, or to tap Edit to make changes to existing playlists for those times when you want your favorite tracks to be at the top of the list. Sadly, Smart Playlists can’t be edited (for reasons unknown), but any of them can be deleted by tapping and holding your finger until the familiar little “X” pops up.

49. Music: Group By Album Artist

If you have a lot of albums which feature tracks by more than one artist head to Settings > Music, toggle “Group By Album Artist” ON and albums with multiple artists will now be represented by one listing in the Music app.

50. Music: iTunes Match

If you’d rather have your entire iTunes library available in the cloud at all times and are willing to pay $24.99 per year for the privilege, iOS 5 is happy to oblige. Head to Settings > Music and flip the iTunes Match switch to on. Note that any synced music will be wiped off your device, but the good news is you’ll see your entire library appear in a moment, ready to download at will. Only want to see the tracks you’ve downloaded? Toggle “Show All Music” to off.

51. Music: More EQ Presets

Head to Settings > Music and tap the “EQ” field, where you’ll now find 22 different settings available for your listening pleasure. The only thing that would make this feature cooler is if it was accessible directly from the Music app for on-the-fly changes.

52. Notes: New Fonts

iOS 5 finally brings some much-needed font relief with two new choices: Noteworthy and Helvetica. You can pick these in Settings > Notes, although it’s odd Cupertino won’t let us choose from the full range of fonts included with the operating system.

53. Notification Center: Hiding Widgets

By default, iOS 5 comes with two Apple-supplied widgets activated in Notification Center: Weather and Stocks. If you don’t care how fast Netflix stock is diving into the toilet this year, head to Settings > Notifications, tap on “Stocks Widget” and then change “Notification Center” to off. You’ll no longer see it, and the widget will be banished to the bottom of the list.

54. Notification Center: Hide Apps From Notification Center

Angry Birds taking up too much space with its messages in Notification Center? Simply head to Settings > Notifications, tap on the offending app and slide “Notification Center” to off. You’ll still get notifications, but they won’t linger in Notification Center from now on.

55. Notification Center: Manual Sorting

Apple has included the ability to manually sort Notification Center entries. Visit Settings > Notifications and tap “Manually” under Sort Apps. Tap the Edit button and you can tap, hold and slide your favorites to the top (where they’ll now appear higher in the list) and put the less-important stuff below.

56. Notification Center: Number of Recent Items

Maybe you want Angry Birds to show up in Notification Center, but limit its presence to fewer notifications? Head back to Settings > Notifications, tap on the app and then “Show” and choose from one, five or 10 recent items to be displayed (five is set by default).

57. PC-Free: iTunes Backup

Now that you’ve turned on ‘Cloud backup, you’ll no longer be backing up your device via iTunes on the computer – that is, not automatically, anyway. You can still select your device in the sidebar while it’s either plugged into ‘Tunes or available via Wi-Fi, hold down the Control key and select “Back Up” to initiate a computer-based backup – because one is never enough when it’s your valuable data at stake, right?

58. PC-Free: OTA Software Updates

Apple is a little bit late to this party — Android and other mobile device owners have long been able to update their gear over the air, using nothing but their wireless connection. Now when you head to Settings > General > Software Update, you’ll be able to update the device with no iTunes required. Even better, Apple plans to notify users about updates via push notifications. Sweet!

59. PC-Free: Rename Device

It’s a small but subtle change: Going to Settings > General > About you can now tap on the device name and change it, without having to do the deed from within iTunes. A little bit more of the “PC-Free” that Apple keeps preaching.

60. PC-Free: Use Device While Syncing

iOS 5 finally brings the ability to actually use your device while it’s syncing with iTunes – no more twiddling your thumbs waiting for a sync to complete before you can sink your claws into that new app you just purchased.

61. PC-Free: Wi-Fi Sync

Apple may be shilling ‘Cloud as a way for us to push purchased content to any device we’d like, but old habits die hard. That’s why we really dig the new Wi-Fi sync option with iTunes. Check the “Sync with this iDevice over Wi-Fi” option in iTunes while your device is plugged in via the dock connector, and from now on you can cut the cord. Head to Settings > General > iTunes Wi-Fi Sync from your device and tap “Sync Now” and you can even initiate a sync while you’re away from the computer (but in the same network).

62. Phone: Location Display (iPhone)

iOS 5 now displays the city and state underneath the Caller ID for an incoming call. This feature also shows up for missed calls, as shown here. Quite handy!

63. Photos: Edit Albums

iOS 5 brings the ability to edit pictures right on your device, but it also offers another convenient change: Allowing users to edit albums as well. Tapping the new Edit button allows you to Add a new album or rearrange the order of current

64. Reminders: Calendar Integration

Not an iCal user? iOS 5 now allows for deeper integration with Google Calendar and Microsoft Exchange, which includes the new Reminders app. With the app open, tap the Lists icon in the upper left corner and you’ll see a list of available calendars that can be utilized, based on what’s set up in Settings > Mail, Contacts, Calendars. Make your selection and new reminders will go to that calendar instead.

65. Reminders: Default List

If you have more than one account set up for your reminders, it’s handy to be able to pick which one iOS 5 will use by default. That’s where Settings > Mail, Contacts, Calendars comes to the rescue -scroll to the bottom and you’ll see a “Default List” setting to select the one you want. While you’re there, be sure to tap “Sync” and choose from All Reminders or a range from two weeks to six months prior.

66. Reminders: Location-Based Reminders

iOS 5 can now remind you about something based on your location. Tap on a reminder then “Remind Me” and switch on “At a Location.” By default you’ll see your current location, but you can choose an address from your address book. Now choose whether you want the reminder when you leave or when you arrive and tap Done to commit the change.

67. Safari: Remove Website Data

Want to know how much of your precious storage space a particular website is taking up on your device? Browse to Settings > Safari > Advanced and tap “Website Data.” Each site that stores data will appear there, and you can tap Edit to delete the worst offenders (which will be displayed at top)-or scroll all the way to the bottom and tap “Remove All Website Data” to get a clean slate.

68. Settings: Manage Airport Networks

As part of Apple’s new iOS 5 initiative, wireless AirPort networks can now be managed right from your device. Go to Settings > Wi-Fi and tap to expand your network of choice. At the bottom you’ll see a “Manage this Network” option, which will open the free AirPort Utility app from Apple.

69. Settings: Multitasking Gestures (iPad)

Apple has added the ability to use four or five fingers for a few slick gestures on iPad: Pinching to the Home screen, swiping up for the multitasking bar or swiping left or right between apps. Turn on the multi-finger fun by heading to Settings > General and toggling “Multitasking Gestures” on.

70. Settings: Personal Hotspot (iPhone)

If you’re signed up for a tethering plan through your carrier, you’ll now venture into Settings > Network and tap “Set Up Personal Hotspot” to make that connection. A small but essential change for tethering fans using iOS 5!

71. Setting: System Services in Status Bar

Apps that are using location services display a status bar icon when in use, but did you know that Apple has background stuff going on that doesn’t reveal such activity? You can correct that situation by going to Settings > Location Services > System Services and toggling “Status Bar Icon” to on for compass calibration, diagnostics and usage, location-based iAds or setting your time zone.

72. SIRI: Raise To Speak (iPhone 4S)

There’s not much to tweak once you’ve started up Siri on the new iPhone 4S, but there is one small setting worth noting. Go to Settings > General > Siri and you’ll spot a setting called “Raise to Speak,” which is on by default. This controls your ability to speak to Siri by holding the iPhone 4S up to your ear, but if you don’t like it, simply toggle the switch and the Home button will be your new best friend.

73. Sound: Change Ringer and Alerts With Buttons

In the past, iOS device owners had no choice but to use the volume buttons to adjust ringer and alert volume on the fly. With iOS 5, you can now toggle the buttons off and retain a preset volume using the Sounds slider. Head to Settings > General > Sounds and switch “Change with Buttons” to off to do so.

74. System: Multiple Apple IDs

Apple has a real mess on its hands with Apple IDs, especially for longtime iTunes Store users who also have a MobileMe account that’s been migrated to iCloud. Thankfully, iOS 5 is pretty forgiving when it comes to using multiple Apple IDs — you can use one for iTunes and App Store purchases, and another for FaceTime or iMessages, for example.

75. System: Rounded Toggle Buttons

Did you notice a subtle change in the appearance of the toggle buttons with iOS 5? Your eyes do not deceive you: Apple has changed them to be more rounded in appearance — even as OS X Lion goes in the opposite direction, with more squared buttons.

76. Twitter: Find Me By EMail + Location

There’s not much to iOS 5′s new Twitter integration—sign in with your user name and password, start tweeting. But it’s worth a trip back to your account settings under Settings > Twitter > [AccountName) to make sure “Find Me by Email” is flipped on (so other folks can find you in an email search) and also “Tweet Location” so the built-in Twitter will automatically pull your current location and tag it before sending a tweet, should you want it to do so.

77. Videos: New App (iPhone)

Gone is the familiar old iPod app which housed both music and videos under one roof, replaced by the iPod touch and iPad method of having separate apps for different tasks. Now if they’d just let us resume videos watched via Home Sharing…

78. Videos: 1080P Support (iPhone 4S, iPad 2)

Support for 1080P HD playback is baked into the native Videos app that’s part of iOS 5, although it requires compatible hardware—which at this point narrows it down to the iPhone 4S and the iPad 2.

79. Weather: Current Location (iPhone/iPod touch)

One of our favorite new iOS 5 features is a simple one: The first location in the Weather app is now your current one, which means it will refresh based on where you are. Of course, you can still save favorite locations, but no longer will you have to play a guessing game when it comes to getting the weather while traveling.

80. Weather: Hourly Forecast (iPhone/ iPod touch)

Likewise, you’ll no longer be stuck seeing only the current weather conditions with iOS 5— swipe down and you’ll see an hourly forecast so you’ll always know what to expect, at least for the next 12 hours.
