Hey guys, first post. Last night I tried to use Pwnage tool 4.1 to jailbreak and subsequently unlock my iPhone 3G. It was previously running on firmware 3.1.3, as I was afraid to try and do the jailbreak and update, as something might go wrong. Well anyway I read up on using Pwnage tool and felt cofident so I went ahead and built the custom firmware. The first time I restored to the custom firmware, the phone worked, but it was extremely slow and working very abnormally. So I then tried to but the phone back in DFU mode and restore using the custom firmware that is automatically generated in Pwnage tool (i.e. not using expert mode). The phone is in DFU mode as iTunes detects a phone in recovery. I then try and restore using the firmware but I keep getting error 1600. I tried unplugging and re-entering DFU mode a bunch of times but the same thing happens. Also, I tired holding the home and power button for like 20-30 seconds and it enters recovery mode (I see the default pwnage tool recovery screen), but then when I try to restore from the custom firmware, the process goes a little farther but then I get error 1603. If any of you guys has any idea of whats going on or have any suggestions on how to fix this problem, please let me know. My phone is rendered useless for the time being. Thanks!
