I have jailbroken my device many times and asked before on this forum if that was OK. everyone said not to worry. so i recently unjailbroke again to see if there was any difference in battery life, etc. I determined there was not and jailbroke again. I restored the iPhone back to 3.0 using an IPSW I had/found, then set up as a new iPhone in iTunes. I then, within iTunes, updated to 3.0.1. and jailbroke using redsn0w .08. at some point after it completed and I was playing with the phone, the device went to th Apple boot screen, then the screen went black. nothing would cure it other than another unjailbreak. I really want it jb again so did I do something wrong? I am pretty familiar with the process and have done it successfuly mny times. Perhaps I was using an IPSW that was corrupted somehow? Perhaps, if you think that's the case, someone can poiint me to an IPSW and copy of redsn0w that is 100% stable? Thanks.
