I bought mine outright through T-Mobile and had to call to get it unlocked. Because I paid for the phone in full on purchase, I did';t have to wait the 40 days to get it unlocked. My phone was unlocked the same day I called and I got the email saying it was unlocked about three hours after calling. I verified the phone was locked the day I got it by inserting a AT&T sim. It said the sim was invalid.
Once the phone was unlocked, all I had to do was insert the AT&T sim, enter my iCloud email and password and it began working.
To get the unlocked version from the start, you have to buy it from Apple. T-Mobiles iPhones are all locked if bought from T-Mobile.
