Hi, I recently bought a 16gb iPod Touch and successfully jailbreak'd using Oktoprep & upgraded to 1.1.2. Was using fine for a couple of weeks with only a few iPhone apps like Mail & Weather. One morning picked up the iPod to drive to work & it wouldn't turn on, even though I knew it was charged. Done a full reboot (held Home & Sleep) and the iPod started up & I listented to a few tunes in the car. However, when the iPod went to sleep, I couldn't wake it up & again had to do a reset. I did a forced restore with 1.1.2 but I still get the sleep problem - the iPod won't wake up & I have to do a forced reboot every time. I also can't do a downgrade to 1.1.1 (with the same firmware I used to first jailbreak the device). When I try to downgrade the iPod goes into restore mode but then the screen freezes & flashes & reboots back to the 'plug into iTunes' screen. I've tried to downgrade on a variery of computers, both Win & OSX, but I still get the same error. I also get some crash logs occaisionaly when syncing with iTunes......... Any help?
