As well as a RAM Mount (suction) for a general purpose internal/external camera mount:

I also use the RAM Mount for my iPhone when running Harry's Lap Timer, to insure accurate GPS and accelerometer data:

NOTE: The form-fitting mounts are the only ones that work. The "X-Grip" mounts are much too loose to hold the phone securely at speed and while cornering.
