How do I de-activate the dial last number feature.

[Downtowner]

When I put my Treo 750 in the holster I bought, I sometimes depress the green phone button by mistake, dialing the last number I called. This could be embarrassing! Can anyone tell me how to disable this feature?

Don't know how to de-activate, but there is a simple fix. Lock your keys before you drop it in your holster.

Ctrl + End will lock the keys and screen immediately instead of waiting for the system to fall back to standby on it's own. I got into the habit of locking mine before I put it in my pocket for the same reasons.
