The iPhone has an iconic look, but not everyone is content with the standard black and white casing. A report in the New York Times details how a growing number of people are risking their warranty by modding their phones. It's not just individuals working alone in their garage, but a new set of companies whose primary business is to help you tweak your phone's appearance

There's Zeetron which offers an iGlow modification that'll light up the Apple logo when you are using your phone and Material6 which sells kits to replace the back of your iPhone with a rustic, wooden casing.

It's the predictability of the iPhone that's allowed these cottage companies to flourish. Unlike Android phones which come in a variety of sizes and shapes, the iPhone's dimensions have remained relatively consistent. Of course, there was a big jump from the iPhone 3GS to the iPhone 4, but among five models that was the biggest deviation from a consistent product design.
