Topic says it all, really. I noticed yesterday that I could still ping the ipod 10 minutes after it should've been in sleep mode. I woke up this morning, and the iPod was off... Odd. Started it, enabled "numeric battery" in SBSettings and it showed 2%. It was 80%+ when I went to bed last night... I can only assume Wi-Fi is responsible for this. Any ideas how to troubleshoot this? I jailbroke as soon as I verified everything was restored and working (i.e. within half an hour) so I don't know which is to blame.
