First off, if I'm not in the right place, I apologize. I've been looking for hours for the answer with no luck, so this is a last resort. I was downloading PDAnet this morning in cydia and it asked me to reboot my iphone. I did and ever since then it has been in a constant cycle cutting off and turning on. It stays at the apple logo with the loading wheel. I can put it into recovery mode or DFU mode but itunes has stopped recognizing my phone. I plugged in my sister's phone to see if it was my computer and it worked fine. I've checked the drivers and just about everything else and right now I don't know what to do. I have an iphone 3gs running 4.1 and I jailbroke it with limera1n. Any help would be greatly appreciated.
