Some iPhone 4S owners can now download iOS 6.1.1. It seems to be rolling out, but may not yet be available to everybody.
The update, according to the notes, “fixes an issue that could impact cellular performance and reliability for iPhone 4S.” This is an issue we heard about earlier today. Looks like this may be the fix they were talking about. Whether they knew it was coming, or were just sending out a warning isn’t clear.
It’s a small, 23MB update.
