I have iPhone 3G 2.2 firmware used to have AT&T service. Now I don't have service nor SIM card. I would like to Jailbreak and I tried QuickPwn many many times but not successful at all. It says not able to get to DFU mode. I am using Mac OS QuickPwn version. Can someone give me step step instructions including QuickPwn download site as well. This will make my weekend if I can unlock and get my iPhone to work with any GSM provider. Is it better if I upgrade my iPhone to 2.2.1 via iTunes and then Jailbreak? When I tried QuickPwn to Jailbreak, many times iTunes keeps coming to bug me to ask if I want to upgrade to 2.2.1 firmware or trying to sync. Is it normal while we do the Jailbreaking process?
