MacRumors reports that the third beta of iOS 7.1 includes a feature to allow users to delete unwanted over-the-air files that are automatically downloaded whenever an iPhone is connected to a power source. By having the ability to delete the files, users who do not wish to upgrade their devices to a new version of iOS can free up storage space on their devices.
In the past, OTA update files could not be removed. This received quite a bit of unwanted attention in September of 2013, after iOS 6 users were faced with either updating to iOS 7, or losing 3.1GB of storage space to the installation file.
Users with iOS 7.1 Beta 3 who have yet to install the update can find it listed in “Settings” -> “General” -> “Usage.” There, it can be removed just like any other app of file.
Since iOS 7.1 is currently in Beta, there is a real possibility that this feature might not make the cut before the OS update is released to the public. However, it’s likely that many users would welcome the inclusion of this feature in the final product.
