iSkin on Thursday introduced the solo “bodyguard” for the iPhone 3G, a new form-fitting case. It will retail for a cost of $29.99.

The iSkin solo features a high-gloss finish and comes in four color options — black, white, red and blue. It incorporates a non-slip grip, and provides you with full access to controls.

The case is hot and cold temperature resistant, sleek and protects the iPhone against impact, scratches, dirt, dust and other hazards.

This is yet another case-related accessory for the iPhone, which is slowly becoming its own market in itself.
