I've just purchased an iPhone from a (dodgy) friend. My only saving grace is that it was really cheap! The phone works fine but it will not recognise any SIM cards. I have unlocked it correctly & I have jailbroke it too. The phone can pick up a WiFi signal, but as I said before I can not use it as a phone! I'm beginning to think that it is a stolen phone. Is there any way I can get the phone working or are iPhones useless as phones if they have been reported as stolen?
