I have an iPhone 5S running 7.0.4; it was set up from my old iPhone 5's restore and worked fine until I installed 7.1b2 (UDID registered) ... Suddenly my outgoing FaceTime audio stopped working (FaceTime Audio worked, but FaceTime video calls had no outgoing audio - my callers couldn't hear me, but I could hear them, unless I used headphones with a mic). I deleted all settings and that did the trick, for about a day. So I finally restored back to 7.0.4 and restored a pre-beta 7.1 backup. The exact same thing kept happening, so I finally just did a DFU restore and now I'm having yet another problem. My iPhone 5S, freshly restored to 7.0.4 and set up as a new phone, refuses to sync iCloud keyboard shortcuts. These are the troubleshooting steps I've taken: reboot iPhone hard reboot (holding power+home) reset all settings delete iCloud account disable syncing Documents and Data reboot again reset Documents and Data at iCloud.com reboot all iCloud devices Nothing helps. My iMac (running 10.9.1) and iPad 3 (iOS 7.0.4) are able to sync keyboard shortcuts just fine; only the iPhone 5S - freshly restored! - is unable to sync keyboard shortcuts. Any ideas? This is driving me nuts. First no outgoing audio in FaceTime and now this.
