PDO is taking pre-orders for its newest iPhone case, the TopSkin. Unlike most cases, the TopSkin does in fact cover several controls while remaining functional, including the Home button and the power and volume switches. The headphone jack and dock connector are similarly covered, but must have flaps opened for use. Normal openings are present for the camera, speakers, microphone and vibrate switch. A film covers the touchscreen. Another feature of the case is its belt clip, which can be adjusted to any preferred angle. The TopSkin should ship in mid-October, and will cost $20.
