WWDC is just around the corner and leaks have started to begin.

According to the MacRumors, one of there reader discovered that while updating applications from iTunes he got the below mentioned message

Or if your device has Automatic Download enabled for apps, your updates will download to your device without having to sync.

And till now this kinda feature is not found in iOS 4, so it will be probably coming in iOS 5 i.e our applications will be updated automatically when they are connected to Internet. Currently now we have to hit update in App Store to update our applications but in iOS 5, this job will be done automatically. It could also be a testing of iOS 5 by Apple. This also hints the rumors of AirPort Extreme and Time Capsule.
