Anyone else concerned about this? My phone's gotten pretty toasty after driving, on a sunny day with and without running Navigation (which doesn't seem to make much of a temp. difference). Would long-term sunlight exposure be enough to set off the Bionic's "Cool Down" mode, or be able to damage the phone? I hope I'm just being overly paranoid, but I've actually been tempted to construct some kind of shade that attaches to the car dock, to cut down on the exposure.
