I bought a 64GB iPod Touch at Target in mid October and now it won't wake. The battery was full when I went to sleep. Has anyone else had this happen? Returning is easy enough but I'm concerned about my info and emails on it. Is there any way to wipe it? I do have a passcode on it but this still concerns me. This is very disappointing. I have one of the first 1g touches and it still works.
