My brother tried to jail break my 4th gen 32gig iPod touch and, stated in the question, it was a bad jailbreak and now my iPod will not connect to my schools wifi. Yes, I have tried restarting my iPod, reseting the settings, forgetting the network, turning wifi on/off, and all of the other 'quick fixes' out there. Needless to say, they didn't work. I'm not in favor of reformatting my iPod, but it is a possability. Thank you.
