Same problem here, except I have 2G 8GB iPhone running 3.0 It was having problems, so I decided to reset it and now it doesnt turn on. I'm getting to the apple logo, but then it just shuts down.
So couple questions?
1. Fixable without losing all data? Or without upgrading or anything?
2. Can I do the newest fw jailbreak/unlock for Windows? and with what application? Blackrain or w/e?
