The Frugal And On-The-Cheap Thread
 

Here is my 5.00 contibution, a pair of vinyl covered clamps that hold my iPhone for making vids of my rides and as a boredom damper for riding nowhere fast on the winter trainer.....

I usually carry my iphone on the belt clip on the back for rides, though. I wouldnt use the clamps for rides due to vibration and jarring. Sure does work well for vids. :)
