While most of the attention in the iOS 6 beta has been directed towards Apple’s removal of the YouTube app, there are also a number of subtle changes in the pre-release software that deserve to be noted. The latest feature to be uncovered in the iOS 6 beta is the ability to download app updates at a much quicker pace in comparison to older iOS versions, particularly iOS 5.1.1. Brazilian site BlogdoiPhone has created a video that shows how long updating the official Podcasts app takes on iOS 5.1.1 and iOS 6, with the latter version taking significantly less time to complete the download.
Perhaps this is a sign that Apple is testing delta updates for apps, meaning that only the updated or changed parts of the app package are required to be downloaded by the end user. Apple already offers over-the-air delta updates for iOS software updates, saving iPhone, iPod touch and iPad users a tremendous amount of time over downloading the entire software version over again. If delta updates for App Store apps proves successful for Apple, the Cupertino-based company might opt to expand the feature to third-party apps by developers.
