Apple Releases iOS 5.1.1 with HDR, AirPlay, and Safari Syncing Bug Fixes

Oops. Attempting to upgrade my 4S to 5.1.1, it's been well over an hour and progress bar on iPhone (Apple logo) is stuck. There are three reports of similar hangs from other users.

No response on the Apple forum. Hoping for some advice from another user who has seen this problem and gotten past it.
