Before I am massacred I have done a search and couldn't find the hack! I am new to iphone hacking so please bear with me. I have bought an iphone 3g on 02 contract and would like to unlock it so that my husband can put his t-mobile sim and use it. Can someone in plain english for thick people like me walk me through the process. I have NOT updated it to 2.2.1 which I assume was the right thing to do. Help would be appreciated as I don't want to be beaten by this phone by giving in and paying £15 for someone to unlock it. Many thanks.
