I'm so used to my Treo 600 where I used to use the "Sun" key for Goodlink as well as to turn the screen back on or turn the screen off.

Since I've gotten my 650 I keep hitting this button, as it is in the same place as the sun key, and it hangs up my call all the time.

Is there any way to remap this key or at leat turn off the ability for it to hang up my phone?
