I'm going camping for two nights, and apparently the temperature is supposed to get to over 100 degrees the weekend I'm going. I'd be sleeping in a tent, so I don't have an air-conditioned place to put my iPhone, and during the day I'm going to be at the beach, so my only options for then are in my car or with me on the beach. Would putting it in the glove compartment of my car be fine? Or would that just make it hotter? What about keeping it in the trunk with a battery-operated fan blowing on it, if I want to be ultra-paranoid? Or would it be fine on the beach even, kept in a plastic bag so that sand doesn't get on/in it, even though the temperature may be over 100 degrees?
