Well, iOS 6.1 is still pretty young, but 6.1.1 is already hitting the airwaves. At least for some iPhone 4S owners that is. We've been able to confirm availability of the upgrade on multiple 4S handsets, but have not seen it yet on an iPod touch or any other iPhone model. The notification screen does specifically call out the update as fixing issues relating to "cellular performance and reliability" on the iPhone 4S, so it's entirely possible the update will be for that device only.
