Hi! I've got a question. My friend has an iphone, he just bought 3gs 32gb. It doesnt support his sim. I am going to try unlock it, but i dont know which firmware it has on, is that important to know or it doesnt matter? Is there anyway I can just unlock it, and let it be as a regular iphone, rather than jailbroken? I am not sure i rephrashed my questions correctly, if neccessary do please correct me. Any help would be much appreciated. Thanks!
