Apple has seeded the next beta version of iOS 5.1, which is iOS 5.1 beta 3 to developers for testing the next update. According to MacRumors, the next version is build 9B5141a. The previous version arrived as build 9B5127a, which released iOS 5.1 beta 2 in December. This new build has been reported to allow users to switch on and off 3G services, again. Back in October, it was reported that the iPhone 4S had been missing the 3G toggle switch. The switch is back with the old warning that while 3G is faster, it consumes more battery.

The release notes for iOS 5.1 beta 3, include a note about a new API, which is designed to help developers flag files and directories that should not be backed up. The addition says, "iOS 5.1 introduces a new API to mark files or directories that should not be backed up. For NSURL objects, add the NSURLIsExcludedFromBackupKey attribute to prevent the corresponding file from being backed up."
