iOS 5 for iPhone and iPad walkthrough
By Rene Ritchie, Wednesday, Oct 12, 2011

iOS 5 is perhaps Apple’s most audacious update since iOS 2, which introduced nothing less than the App Store and MobileMe. The features are almost an embarrassment of riches, including unobtrusive Notifications, the carrier-consternating iMessage, Twitter integration, a location aware Reminders app, and an entirely new UI paradigm in the artificially intelligent Siri voice control system for iPhone 4S.
And for the first time what’s happening on the outside is just as compelling — iCloud. Apple called it “cutting the cord”, severing the post-PC from the PC, and the iPhone, iPod touch, and iPad from their subservience to Mac and Windows.
But is it truly transformation or just another bold yet ultimately evolutionary step forward? Let’s find out.
Note: This walkthrough is based on the iOS 5 gold master (GM). While I don’t expect any changes in the release version, I’ll update if any do show up. So, please consider this a living, breathing document for now, and expect additional screen shots, comments, and corrections going forward.
