iOS 5 to Finally Deliver Over-The-Air Updates?
According to 9to5Mac , Apple started to negotiate with Verizon about supplying  over-the-air iOS updates starting with iOS 5.
The  over-the-air update system will allow users to download straightly  to their phone over 3G or Wi-Fi the iOS the iOS update and also it will give the opportunity to update their phone to the latest version without connecting to iTunes. This feature was already offered by the Android devices.
Because of the high requirement of bandwidth, Apple has to negotiate contracts with individual carriers to make it possible. We should remember¬† that Apple’s iOS is¬† able¬† to run such a system . The Apple TV which is based on iOS 4 gives¬† “over the air” updates with no iTunes syncing required and also t he Apple TV, however, stores little customer data so backups won’t be a problem¬† with iPhone and iPad devices.
