I have searched all the threads and there seems to be many different troubleshooting techniques. My phone is stuck at the apple logo after turning the phone off. I have been trying for hours and hours just to turn it back on. So far I have no luck. I need my phone so I am willing to do a clean restore and be on 3.1.3. I am currently unlocked and jailbroken using blackra1n and on 3.1.2. I have tried resetting it by holding the sleep button and home button. That doesn't seem to work and I tried holding the home button while connecting it to the computer, but that doesn't work either. I really need my phone and I hope that you guys can help me out. btw. I am using a 3g.
