if there's been a thread on this already, i'd appreciate a re-direction. i couldn't find anything from a quick search... i have a 10GB 3rd gen iPod. i use it every few days. if i don't use it for more than a day or so, the iPod resets itself (the black apple logo screen for a while, then the main menu) before it becomes accessible. is this a known problem? after use, i turn it off by holding the play button, then i turn on the hold switch to "locked." the iPod self-resets (a day or more later) when i move the hold switch from "locked" to "unlocked."
