Hi, I was looking to get one of iPhone 3G 8GB from ebay, and found good deal. It was factory sealed and about $650. He says activation will be no problem which is my main concern, of course and said my pay as you go sim would work right away. I asked more and he sent me private email saying..well I will not post our private messages but this is the method he gave me 1. Take out the inactive SIM included in the package and replace it with a gophone SIM of your own. 2. Take the phone and plug it into iTunes for the first time. 3. iTunes recognizes your phone and your phone is ready to be used. and it is good to go. Remember it's factory seaeld iPhone 3G 8GB and how did he get one for brand new not even unlocked and I can activate so easily? Please any advice is welcome!
