I have an iPhone 3GS and for two days now, it will all of a sudden lose service and then restart which of course means rejailbreaking it. The first time this happened I had to try about four times before I successfully re-jailbroke it with blackra1n but the second day this happened (yesterday) I was not able to re-jailbreak no matter how many times I tried (which was probably 15-20 times) because the phone keeps on rebooting, even in the midst of recovery mode. It goes through the jailbreak and then after the GeoHot screen, restarts with the apple logo and returns to the recovery mode screen. I have had the phone since Feb and have never had problems jailbreaking it (which I've only had to do 2-3 times). If I Restore the phone it will update the software and I won't be able to use it (I need it unlocked because I am using it abroad). HELP!!!!!!! Thanks!
