hey everyone! i just got a brand new 42-weeker iPod touch yesterday. i got it plugged in to my laptop and tried to pick it up, but i think i got a little jolt! my fingers weren't wet at that time. it was just a prickly sensation, but i'm worried! i plugged it into my desktop as well, and got the same problem! should i hand it in to ask for a new one, or is this problem experienced by all? i haven't got any film lining over the metallic back, if that's an issue.. advice please fellas?
