I wanted to see for myself if this works with my recently purchased 1020. So I called AT&T this evening and the service rep directed me to their unlock request website, basically telling me that I can just go to this site and put in a request for the unlock code, I was a little skeptical because that just seemed to easy. I go to this site and put in my information but I got the message "this phone cannot be unlocked at this time" or something to that effect....So I call AT&T back, got a different service rep, again explained to him why I needed the code, this rep was completely different than the previous one I encountered. He basically just had to check my information, make sure the phone had not been reported lost or stolen, check to see if I had an outstanding bill since AT&T is my carrier, after about 5 minutes, everything checked out and he asked me if I had a pen available to write down the code, or he could send it to me via text message! Got the code and tested it out using a sim card I had from Europe, and it worked! So, like I read in previous comments, I guess it depends on who you talk to at AT&T!
