Received my iPhone 5S a couple of minutes ago (posting this from it). I got the T-Mobile Version to use with my AT&T SIM card and it is indeed unlocked. So the T-mobile version is unlocked and not tied to T-Mobile.
Arrived about 5 minutes ago. It was however, driving around all day in a UPS truck in Dallas, where it's in the 90's, so I'm letting it cool off for a little bit before I fire it up. ha.

Thank you, thank you for posting this! I have one on the way from Apple for T-Mobile (unlocked) but I want to see if it will work on AT&T as I may have to go back to them in the future. Apple has changed there website now to read no contract so I was worried. And of course they all (t-mobile & Apple) all have different stories. Apple has told me it should work with both.
When I unlocked my 4s from AT&T to go to T-Mobile it messed up my Group MMS so I can not reply to them. I don't want this to happen the other way around or something worse. I just wanted an unlocked phone to use with either so thank you again!
