How do i import contacts from my g1 to my blackberry?

Just got a blackberry, when I put my sim card into the blackberry it transfers some contacts but not all..on the G1 contacts settings there isnt anything to select to backup/save all contacts...any advice?How do i import contacts from my g1 to my blackberry?
You have two very easy ways... but both require data, so I really hoping you have internet on the device still. There is an application in the market (I think it is Contacts2SIM, you can search for SIM and it should come up) and then download it, and it will allow you to save contacts to the SIM card on the G1. Or you can simply get the Google Sync application for your Blackberry, then you can sync your contacts from the Google account right to your phone :) It's pretty awesome.
