Slowly and steadily, we're beginning to see more apps for the iPhone begin to take advantage of iOS 4 with its compatibility for multi-tasking. Skype for iOS is the latest, and probably one of the most highly regarded apps, to finally make the switch as version 2.1 will enable it to run in the background. Users will now continue to receive Skype messages and calls if they happen to exit back to the home screen or lock the handset. As much as this is seen as a miraculous thing, it's nothing too special for users of rival platforms like Android and Windows Mobile. However, the biggest feature that users are waiting for is still non-existent as there is no support for video chat through Skype via the iPhone 4's front facing camera. Now you'll never have to worry about an important message if you accidentally exit out of the application.
