Tao got an iPhone from his uncle ages ago. It ended the good old days of using his B&W NOKIA. Tao had thought to get a cover, but the price made him hesitant.
As an alternative, we bought some felt pads. The idea was super simple: if they can protect pavements from table legs, and walls from chair handles, they should be able to protect the back of an iPhone.
We put two on the back, using the height of them to lift the phone. In this way, the camera is always away from the table, thus protected.
In addition, the roughness of pad adds a good amount of friction to the phone. It should work nicely for most people unless you have a push-everything-down cat, as we do. In general, Tao felt happy about his pads. They are effective, cheap (2 pads cost only 1/20 of a normal cover), and sometimes could be even funny!
