I recently updated iPhone 3gs for new iPhone OS firmware 3.1.2 and want to unlock it. I tried the traditional method to unlock it by putting to restore mode but it didn’t work for the iphone. I have heard about the Pwnage tool but do not know how it works. So tell me how I can unlock my phone as I have searched it everywhere but could not find anything. If someone has any idea or know about how to unlock iPhone 3g 3.1.2 please share. I would really appreciate
