This has only been in the last week or so - my 4G iTouch on/off and volume buttons seem to have stopped working. At first it was intermittent (I think they worked again after being connected to the computer)... I'm not sure if it's related but it seems to happen after I've had it hooked up to an iTouch FM connector in the car (powered by the cigarette lighter).... I'm about to hit the hay (not US timezone) so will see if how it is tomorrow. Connecting it to my Mac hasn't resolved it tonite (so far!)... Does anyone have any experience with this and/or ideas, suggestions? I'm guessing that if it's broken the cost to fix it might mean it's time to get an iTouch 5 though actually right now, I'd rather save my pennies... PS, it's using iOS 4.3.3 (I've been reticent to upgrade due to bad battery life and too many reports of iOS 5 and even 6 making - or possibly making - it worse, so I didn't want to risk it). Thanks! Edit to add: PS - the Home button works fine.
