Pocketmax redialer is a good program for automaticly recalling someone that would not pick up the phone. You can activate and deactivate it whenever you like.

here is a link :

PocketMax Redialer

* Redial a busy number automatically at scheduled interval
* Pop-up quick dialer
* Activate / Deactivate via tray (visual feedback of current state)

Just read at Buzzdev there is a program for unlocking the extended rom for version 2.XX of the wizard.

Could be intresting for tweaking a bit more.
