My phone gets dangerously hot. It happens when I'm streaming internet radio with
Kinoma (especially if I'm multi-tasking ie. web browsing) and it also happens when I'm talking on the phone for a while. It got so hot while I was talking on the phone I had to switch to the headset. Today while it was streaming radio I had the phone sitting on a plastic Xbox 360 game case and after a few hours the case started warping and melting. The longer you have the device streaming data it seems the hotter it gets. Definitely think this device could start a fire or cause a bad burn in your pocket if it's there too long. I took the cover off and it seems like most of the heat is coming from the part in between the camera lens and the battery. Expected the heat would be coming from the battery, but it doesn't seem to be coming from there.
Looks like the phone was manufactured 10/7/08.
