In the days leading to WWDC, Apple's iTunes seems to have leaked a new feature that must be coming in iOS 5. A MacRumors reader discovered (and we verified) that when asking iTunes to check your app library for updates, iTunes' update page reveals a new feature for iOS devices. (Thanks Marcelo) The following line has been added to the My App Updates screen:

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

Such a setting doesn't exist in iOS at present, which suggests that you will be able to automatically get app updates to your device. Presently, users must either sync or download the updates themselves manually through the App Store app.

It also suggests that there is an Automatic Download setting for other items besides apps. Apple has been rumored to be making a push into over-the-air updates as well as some sort of wireless syncing. Rumors of AirPort Extreme and Time Capsule updates have also hinted at such a feature.

WWDC kicks off on Monday with a keynote from Steve Jobs who will detail Mac OS X Lion, iOS 5 and iCloud.

Latest Update: Apple has deactivated the Updates page in iTunes for now due to the slip up.
