I was charging my 1 week old iPod Touch 4g, and when I slid to unlock, the icons were wiggling, I slide over the the page with a few apps and all the downloaded apps have an 'X' on them and won't respond when I tap them. I up'd the volume to see if there was any sound, none. I powered down and back up, it went back to normal. What was this, some kinda virus? Apps downloaded (all free versions): Unblock meFree Mirror angry birds FallDown! NightVision I have no wifi, these were from iTunes. Ver 4.3.2 Any ideas?
