Apple‘s iTunes seems to have leaked a new feature that must be coming in iOS 5.

According to MacRumors, the leak was found directly on the Apple iTunes apps page announcing,

“If your device has Automatic Download enabled for apps, your updates will download to your device without having to sync.”

This feature is already being added by Google’s Android mobile OS, which made Apple users anticipate of having this feature.

Instead of manually updating Apple apps by connecting devices to the App Store, the new feature automatically updates existing apps right when a new version becomes available. The change could see iPhones and other iOS devices updating apps without the need for tedious syncing. This could be good and bad, good because it would make app updating much easier for beginners, and bad because some app updates involve unwanted features.

Once an app update is made available, Android allows users to receive notifications on either running an automatic update or manually select which apps they want downloaded, and then proceed onto installing them. It is unclear whether Apple will apply the same model or present a new way of keeping all apps up to date.

Such a setting doesn’t exist in iOS 4. 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. Users have been waiting for this kind of feature for such a long time, and Apple was also rumored to be switching to OTA updates and wireless syncing.

Let’s see what Apple announces at WWDC keynote on June 6th. And if all the rumors are any indication it will be a software heaven for Apple developers and customers. Stay tuned to know more about this feature on Monday.
