I bought this Palm Pre GSM in Germany O2. My Friend bring it from Germany.

After I used it, I found a problem that on the left-down side back of the pre is very hot when I use the Pre. The exact position get hotter is below the battery and on left side. definitely the battery is going very fast. I just upgade my WebOS to 1.3.1. But the problem still there.

Could anybody help me to find out what's the problem and give me any suggestion? Now I cannot even use it, cz I'm afraid of the heat generate at the back.
