As the Apple App Store continues to grow and users put more notification-enabled applications on their devices, they might find themselves overwhelmed by updates and messages from each app. In Apple iOS 5, this problem is solved with the introduction of a new "notification center," where all app notifications are grouped in one easily accessible place.

Another new native application named iMessage has also been developed for Apple's latest iOS. It's designed to allow Apple device users to communicate with one another in a system similar to text messaging for free. iPhone, iPad, and iPod Touch users with iOS 5 will all be able to use the free service.

For the photo-savvy Apple faithful, additional picture editing options have been included in iOS 5 as well. Designed mainly for the iPad, users will be able to crop and lightly edit their pictures directly on the device.
