More Remote Control possible?

Hello,

I'd like to create a remote control application (to run on a desktop computer) for the T48G

I found the PUSH XML very useful, but there are many functions missing. (like e.g. "backspace" if you miss typed a number)

1. Is there a better way to remotely control the phone?

2. Is there a way to view/retrieve and "mark as read" the call history?
