Im sure this has already been asked, i did a search and nothing came up. I also did a search on google and didint really find anything that was a flat out step by step so i thought i would ask here. If anyone could help me out with this that would be great. Thanks! :)
 
call up t-mobile... tell them you're going to england or something and want to use your phone with a foreign sim card and you need an unlock code, all you have to do is give them the IMEI number of the phone and your email address then they'll send you the unlock code.

you won't be able to use the at&t 3g network, but edge does work.
 
oh ok thanks. its for a friend and he dosent have t-mobile. does that matter?

don't know.... at&t didn't care that i didn't have an account when i called them for an unlock code for my Tilt that my buddy gave me, so who knows lol.
 
I am using my G1 on ATT, no problems..you wont be able to use 3G though.
 
Yeah T-Mobile and AT&T use different frequencies with the 3g technology. I have this problem with the 3g iPhone on T-Mobile.
