Motorola RAZR V3c
I answered you. It won't be the same holster as the original Cingular V3. This phone is 1 millimeter thicker. And based on the style for the Cingular one, it does not have the tolerance built in for an extra millimeter.
The body isn't one mm thicker, the added mm is on the camera.
But based on the dimensions listed, I would assume the whole phone is 1mm thicker. I could be wrong with that one though.
I hope I was able to help you. Unfortunately, this is really all speculation until the phone is actually released.
