my ipod touch has been jailbroken. while my friend was surfing the internet with touch, he installed a program and i don't know what he did. Now, my ipod touch thinks it is iphone and searching any gsm system. the screen writes " Waiting for activation, this may take some time. " and all menus,programs, games disabled. my pc, itunes can't recognize ipod. Force to restore isn't working. what can i do ?
