Waiting for the unlocked iPhone  4S, it seems that Apple is selling them at retail stores only as the “Off Contract”. “Off Contract” device will be sold at full retail price and does not lock you into a contract with AT &T. Pricing for this model is $ 649, $ 749 and $ 849 for 16GB, 32GB, and 64GB models of the iPhone 4S.

The findings cited by 9to5Mac and will also be discussed in the MacRumors forum where several users have noticed that iTunes know them “Congratulations your iPhone is to unlock” message from iTunes:

I really do not know. Part I think it’s sort of error. The only thing I can think of the full price paid and did not renew my contract. Commanded by Apple as well. I wish there was a way I can confirm, but I have no foreign or T Mobile sims laying around lol – BFW122083

The same item appeared to me when I do a restore … I wonder if they like it came from the factory because I pay the full $ 849.99 for iPhone 4S 64 GB for AT & T contract I do not qualify for an upgrade

Common thread is that they purchased as a set off of the contract. Developer @ stroughtonsmith since verified this by purchasing one of their own iPhone 4S.

Meanwhile, Sprint seems GSM Unlocked iPhone 4S also comes with @ grubber can successfully use the SIM card iPhone Sprint Canada in its iPhone 4S. However, Sprint has promised to lock it at a later date.
