iOS 5 also supports iCloud, a new, mostly free service from Apple that replaces MobileMe – iCloud integrates mail, contact, calendar, photo, app, book, and music synchronization without needing a computer.

Notification Center gathers text messages, missed calls, calendar alerts, app alerts and other notifications to the top of your screen, without interrupting what you’re doing.

iOS 5 integrates Twitter support, so you can sign in once and then tweet from Twitter-enabled apps, including Photos, Camera, Safari, YouTube and Maps. Apple is also extending that support for third party apps by exposing an Application Programming Interface (API) that developers can use.

Safari has been overhauled with support for Reader, a feature first enabled in the desktop version of Safari, which lets you view text on a Web page without seeing ads and other distractions. Reading List lets you save articles to read later; tabbed browsing lets you flip between Web pages.

Game Center, Mail, Camera and Photos all sport new features, and AirPlay now lets you wirelessly mirror whatever you do on your iPad 2 on an HDTV using Apple TV. Many other new features have been added, as well – for a sample, visit Apple’s Web site.
