FYI re: overheating, Anandtech reported they ran into it with the Droid Charge (in Arizona): Link:
I just had that today in NYC with my Charge. Definitely not near 104 but my screen went so dark that I had to pull over to see what all the fuss was about because I would have crashed otherwise x). I'll probably be returning the Charge and waiting for the Bionic though. Not having as much fun with it as I feel I should...
