Ive got an ipod touch 4g that has cydia on it, or at least i think it still does. I shut it off one time to get through a device nazi substitute for a class and when I went to my next class the ipod booted to the logo but did not boot or anything close. When i tried to force kill it, it stayed off for EXACTLY three seconds and turned back on. Can somebody provide any hands here? Much obliged.
