I made this cozy for my Google phone, but it fits the iPhone, iPod Touch, and my digital camera. The cozy is about an inch longer than the phone, so the ribbing pulls closed near the top and keeps the phone from falling out without a closure. If you wanted the cozy to be the same size as your phone, removing four rows from the beginning and end should do it.

The pattern is worked in the round on DPNs, and the cables are beginner level. Pattern includes chart.
