OmG my nano won't work anymore! I started charging it for the first time 2 hours ago, and it seemed like it was charging, due to the bolt symbol on the top right corner of the screen. I went to rest a while, coming back afterwards, I noticed the iPod screen was blank, and the computer was still on. I checked the USB connections, all seemed alright. I tried restarting PC, reinstalling the iPod software that came in the bundle, and try using reset on the nano, but it will not turn on anymore. Is it defective? Could it be because I applied the Invisible Shield yesterday and the water might've gotten in? Its been 24 hours though...
