Luxury leather goods maker AB Sutton has introduced its Simple Slip case for iPhone 3G. The Simple Slip is made from kidskin leather with soft silk interior lining. The case comes in two styles — with and without a wrist strap — and customers may also add a silk monogram to the outside of the case. In addition, the Simple Slip features a cable tuck for headphone organization, and dual openings in the bottom of the case for the speaker and microphone. The AB Sutton Simple Slip case for iPhone 3G is available now in a large variety of colors and with a multitude of different silk linings. It sells for $88 without a strap, $108 with a strap; adding a monogram or design to the leather exterior adds $20 to the price.
