Sorry, stupid question here...but I an a new iPhone user. Got a macbook back in march and just officially turned into a fanboy by waiting since midnight for my white 16gb!! Can you charge the phone while it is in fact...OFF ? When I have the phone off, like off off...and plug it into my computer or an AC outlet, it automatically turns it on. Which makes me wonder if it 'has to' be on? My question is, if I plug the phone in, THEN turn it off...is it still charging?
