Just like many in this forum, I also purchased an "off contract" AT&T iPhone 4S two weeks ago at my local Apple store that happens to be UNLOCKED. I have till Nov 15 to return it and I was planning to return it and get an "official" unlocked iPhone 4S once it comes out it November. Well, I got a call yesterday at 2:45 ET and it was not from my local Apple Store but from high up after politely expressing my concerns several weeks ago via email. I am not going to go into detail about the phone conversation and you do not need to believe me but here is the concise version of what I was told (Please read everything): If you bought a iPhones 4S and it was unlocked, Apple will honour the fact that your iPhone 4S is unlocked and you WILL get an UNLOCKED iphone back if it ever needs servicing or it needs to be exchanged because it was not reparable. I was told that Apple looks at the IMEI and Serial number of the original purchase and if that was unlocked in their database, your serviced or replaced iPhone will also be unlocked. I was assured (and even given this person's direct phone number to call this person if I ever had problems) that even though I signed the standard two forms for the "off-contract" AT&T iPhone 4S, my phone will stay unlocked to use with any other SIM card besides the AT&T one. I do not have to return it once the official unlocked iPhone 4S are sold in November in the US. I was also told that sometimes the iPhone 4S might not always recognize all the SIM card setting of a carrier it is not familiar with and that I would then have to go and enter these settings myself but my AT&T "off contract" iPhone will always be unlocked. So, if you purchased an "off-contract" AT&T iPhone 4S at the Apple Store AND it happens to be unlocked, it WILL STAY unlocked. This made my decision very easy not to return my iPhone 4S in two weeks. I am very impressed with Apple. PS: I will not give any further info about the phone conversation I had and you do not need to believe me. All I will say is Apple KNOWS what it is doing and your "off-contract" AT&T iPhone 4S was not unlocked but some accident or some mistake.
