Apple's new operating system for the iPhone, iPad and iPod Touch, iOS 5, has been released by Apple and comes with more than 200 new features. Among the more notable:

iCloud Support
The iCloud service is integrated into some key aspects of the iOS 5 - photos, e-books, device backups, document storage and, of course, the iTunes music program. The most popular iCloud-powered feature amongst users could well be the PhotoStream, an option that can be toggled on or off and which allows users to automatically synchronize photos across multiple devices.

iMessage
iMessage is identical in purpose and function to BlackBerry's popular BBM service. It is like a live chat room between the user and his friend, during which he can text back and forth in real time without using up any text messages.

PC-Free Setup
This option will allow users to activate their iDevices without plugging into a computer. In addition, all back-ups and synchronizations can happen exclusive of any connection to a computer, as long as the user has data stored in the iCloud.

Twitter Integration
The ability to integrate your Twitter account with the iOS 5 is now a reality. Users can share pictures and tweets without having to log in to their Twitter account on multiple occasions. The iOS 5 makes it even easier to tweet from iPhone, iPad or iPod touch.
