I solf my iPhone 4S and the buyer thought the phone was unlocked ... I told him I would go ahead and submit a request to AT&T to have it unlocked. When you sign up it says 5-7 days ... but when I talked with tech support today she said she hasn't seen it take any longer then that or up to 24 hours later. I assume since I put in my request today and it's Sunday I won't see anything till tomm / Tues. Anyone done this service lately and if so how long did it take for you to get your email stating the phone's IMEI is ready to restored and unlocked via iTunes? Thanks so much for the info.
