I'm in the same situation...let me know how it turns out. I've actually bought a magnetic mount thing and it's been working pretty good. there is a really thin strip of metal on the back of the phone which magnets to a disc about 1/8 of an inch thick which is double-sided taped to the dash. it was $10. You can easily get another handsfree off ebay (for REALLY cheap) if you go that route.
