how to get official unlock for old iphone 3gs?
Hi, I switched to Verizon iPhone 4, so my old AT&T iPhone 3gs is no longer in use.
I travel internationally and would like to unlock my old iPhone 3gs so I can use it with sim cards when I travel.
I understand there is now an "official" unlocking that can happen through iTunes. Is that true? How can I do it?
Or is there another way to unlock my old phone that is legal?
Thanks!
iPhone 3GS
