The HTC Desire S is a fairly sexy beast, so it’s a shame to cover it up. On the other hand, it’d be infinitely more depressing if you damaged it. This black jelly cover from Prepaymania (via Amazon) is £1.49 delivered.
The case has a glossy finish, and is specifically designed to fit snugly on your HTC Desire S.
