I have been using a RAM X-Grip with my iPhone's for the last 10 months or so. I have unfortunately ended up with my phones camera failing three times. The first time the camera was replaced under warranty by Apple and the last time they replaced the complete device. I have subsequently done some research and found a lot of cases of cameras failing when phones are mounted on motorcycle handlebars. Be aware that you could damage your phone. I was lucky my warranty covered it.
