Apple released today iOS 7.1. beta 3 to registered developers. The update has a build number of 11d5127c and developers can download it OTA ( over-the-air ) or via Apple’s developer center. NOTE: jailbreakers should stay away from this beta. Updating your device will result in loosing the ability to jailbreak.
The third beta includes fixes for audiobook playbook and iCloud account setup with iCloud Keychain, but there are undoubtedly other tweaks that have not been documented by Apple.
While the “dark keyboard” option that was added in beta 1 and removed in beta 2 has not returned in beta 3, Apple has tweaked the standard keyboard slightly, most notably with a new look for the delete key.
The green color of the Phone, FaceTime, Messages app icons has been toned down slightly, while there is a new “Increase Contrast” section in the Accessibility settings that allows users to reduce transparency, darken colors, and reduce white point.
There is a new option to turn parallax on or off when setting wallpapers.
Beta 3 also includes a new look for the confirmation screen when powering down the device, while the Phone dialer now uses round “call” and “end” buttons rather than large rectangular ones. The incoming call screen also adopts the round buttons as part of a redesign.
