Help Any way to make the optical button into an end call button?

[computerpro3]

This would fix my only complaint about the phone! It's quite annoying when I'm in a call and doing something else on the phone, and I lose the soft end call button and can't hang up.

Thanks!

The call should be up in the notification bar. Pull the blind down to switch back to the call. Or you can hold the home button down to bring up the recent apps switcher.

As far as I know you can't change the function of things like that. Maybe with root.
