So not long ago I jailbroke my 3G with Pwnage Tool to 4.1. Everything went fine I was able to unlock. My battery wasn't that great, but knowing that 4.2 is not long off I'm able to deal with it. My texts were coming in delayed and my calls werent going thru so I turned off my data and have been using wifi and everything has been going ok. The problem that bugs me the most is that my iPhone will reboot every so often. It will work but soon after I open an app it will reboot. It happens usually when I open an app right after closing another. Any ideas on what to do? Should I rejailbreak with pwnage tool and if I do that do I just repeat what I did the first time with pwnage tool?
