i bought my itouch 4g a few months ago and jailbreak it. it worked fine but i accidentally updated my ipod software last week and it became unjailbroken. so i attempted to jailbreak it again myself, and it was fine. when i turned it off tht nite and turned it on again the next day, it was stuck on the apple logo and the loading circle. so i restored it and rejailbreak it, but the same thing happened. wat shud i do?!!
