My brand new HTC Touch recently got drenched in the rains. I removed the battery and showed the set under hairdrier. After some hours I was able to switch it ON but with one problem. The "talk" button on the key pad has become extremely sensitive to touch that even a small bit of paper dropped on it actuates it and the mobile starts calling the last dialled number.
Now how can I rectify this??? Also , When I get an Incoming call the phones vibrations is enough to activate the key pad to "cut" the call even before an audible ring tone starts.

Pls Help.
