I found this at this site... thought I'd share it if any of you have the same issue as me where I needed to enter in extra digits for VM.

Use regedit:
\HKLM\Software\Palm\Varnish\SpeedDialPlugin\Voicem ail\Editable = 1
\HKLM\Software\Palm\Varnish\SpeedDialPlugin\Voicem ail\EditableNumberOnly = 1

Then you should be able to edit the number of the voicemail.

Set EditableNumberOnly to 0, and you can edit the name, additional digits, quickkey etc. So between the two settings you can change Voicemail to whatever you want.

Just can't delete it or assign a contact to it.
