Quick tip from someone who had some problem with getting the pda to dial numbers on phone.
You need a phone that actually allows outgoing and incoming connection.
I used to have the Razar V3, and it was such a pain, was not able to connect. So i got Sony Ericsson 600w. But you can have any Sony Ericsson with BT ofcourse.
OK!
you will need to download the VBDialer :

This will help in getting the pda to connect to the phone.
You have to run this program and test the port that you've configured the phone with.
Once you've done that you save the settings.
And then when you open up contact it'll give you option in menus to dial via VBDialer etc.
Good luck with this. It's really easy, so if you are having a hard time you are doing something wrong. Write back with updates.
