Apple Wednesday released the iOS 5, the latest version of its mobile operating system for iPhone, iPad, and iPod touch devices.

Here is a look at some of the top features in the iOS 5.

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: This is the new messaging service for iOS users. This option is similar to BlackBerry's Messenger service.

Camera Software Improvement: The new and updated camera app for the iOS 5 will make taking a photo a much easier affair. Users can now capture a photo by simply tapping the Home button twice. Users can now also open the camera app directly from the Lock screen. Users can capture movement, through the camera app, simply by controlling the iPhone's volume button

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

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.

Notification center: The biggest feature in iOS 5 is a Notification Center similar to the one found on the Android OS. The users can navigate to the Notification Center by simply running a finger down from the top of the screen, allowing them to access all their notifications from a central location. The result is that there will no longer be any more annoying popups.
