It's not out
Identical on 4S and 5, so that's a somewhat futile exercise. And it's if anything smoother on the 4S than iOS 5 was, with no loss of speed.
Will the OTA update delete anything on my device?
Let me know how long the download takes. Am wondering if I have time durnig my lunch break to do it OTA. Thanks.
Servers will probably get hit harder in a couple of hours though.
