I picked up a Scosche IUH3 vent mount from wal-mart... I think I paid $15. It will work with about any size phone, you can rotate the phone to portrait or landscape and it's easy to put the phone in the mount (just squeeze the sides) and to remove it (just hit the release button on the lower right corner).

As long as the vent clips work with your vehicle's vents I'd highly recommend it.
