At one of my jobs I am forced to leave my phone in the car for about 3 hours. The temperature usually gets down to about 30 F. Will this damage my Eris, it is primarily the screen I am worried about. I've noticed the lcd performs a bit sluggish the colder it is. I read on another site leaving cell phones plugged into the charger might be a good idea but would that really keep the phone from getting cold?
