hey i'm rather new to ipod touch but i have several issues regarding ipod touch.. hope someone can help me! I just bought an ipod touch yesterday..charged it overnight but when i tried to switch on the device, the battery bar still shows empty as though its a newly bought phone without any charging. so how do i start using the ipod touch? 2ndly, can a PC have two itunes? i.e my sis has an ipod shuffle with an existing itunes and should I be using the same itunes as my sister or should I install another itunes? how to do a sync with my PC for my ipod touch? Thanks!!
