You can setup your Twitter account easy enough in iOS Device’s settings. There are now multiple accounts that are supported. After you’ve set things up, when you shoot a picture and take it into Photos app, you’ll see a new option for Tweeting. When you click the Tweet button it creates a thumbnail and you create your message and send away. You get a pleasant little chirp when it goes.
You can send to any Twitter handle in your address book with a @reply, so it goes to only them, unless, of course, you want the whole world to see you in your underwear. If you don’t have them in your contact book, then you can add them if you plan on sending to them often.
iOS 5 Features – Twitter Integration. iOS 5 makes it even easier to tweet from your iPhone, iPad, or iPod touch. Sign in once in Settings, and suddenly you can tweet directly from Safari, Photos, Camera, YouTube, or Maps. Want to mention or @reply to a friend? Contacts applies your friends’ Twitter usernames and profile pictures. So you can start typing a name and iOS 5 does the rest. You can even add a location to any tweet, no matter which app you’re tweeting from.
You can also send Tweets from Safari, YouTube and Maps. This iOS 5 feature for Twitter is integrated into a lot more apps than most people think. You can switch back and forth between the two, camera and Photos app, and send as you take each picture. Watch out, though, you can easily fill up your hard drive taking pictures. This is one of the best iOS 5 features Apple has come out with in a long time. Well worth getting a Twitter account just to be able to use all the iOS 5 features.
