Automatic keylock for the Diamond??
 

I hope this is the right forum. I have tried to find the answer with no success. I have a HTC Touch Diamond and I need a little help on finding a automatic keylock when I make a call. I already have the Slide to Unlock and I know I can put the keylock on by holding down the "hang up" Button. But is there another automatic "Keylock" when I answer the phone? I wear earrings and they always hit the black keys at the bottom and I hang up in others face! Any help??
