Nothing - just plugged it in to the Mac with iTunes running and "Congratulations" popped up on the screen. These phones are not locked. There is no AT&T logo written anywhere at all on the box or the UPC sticker - only on the receipt they emailed me. I took the AT&T sim card out before I plugged it in to the computer.
By the way, what is CL - you wrote they buy iPhone 4 for 3/400 bucks?
Thank you for your response.
CL = Craigslist.
I got a 4S 32GB on Friday and I haven't opened it. I can return it to the at&t store and they will undo everything (I asked this to the rep before I bought).
SInce now that people seem to buy them off contract and getting them in unlocked state, I'd much prefer that. I travel and I would like to save money on the monthly bill as well. I think at&t is too expensive.
What T-Mobile or other MVNO plan are you guys picking?

Exactly. Everyone views products differently for value...but shelling out $650 for a cell phone is ludicrous if you ask me...and it's the 16GB size! Let's face it...the iPhone is really 1% phone and 99% computer/internet stuff...you might as well have purchased an iPod Touch for 1/3 the price and used Skype to make your phone calls.
Skype is horrendous and unreliable as a substitue to cellphone service on a full time basis.
