Has anyone used any of these vehicle mounts for the iPhone 4 from Amzer? This one is just like what I am looking for. (screw in type mount that is specific for the iphone) http://www.amzer.com/Amzer-3M-Adhesive-Dash-or-Console-Mount-P88679.htm I have looked at Arkon, and would like one of those, but I want it to be more specific for the iphone not their slim one that is kinda generic, I don't really like the look of it. Plus they do not have any options that are screw in type not suction cup mounts. This Amzer one looks nice, but I can't find any reviews, and I don't want to spend $20 and have it suck... And I am NOT interested in Proclip, I love them, I really want one, but I do not want to pay that much for it, I just don't have the money right now.
