Sena Cases has introduced three new cases for the iPhone 3G and iPhone 3GS. The Sarach Flip Case is hand-sewn from full grain Napa leather, and features openings for all ports and controls, a hidden multi-purpose pocket in the vertically-opening flap, and a magnetic fastening system—which Apple has warned against in iPhone cases. It is available in four colors and sells for $70. The Sarach LeatherSkin Case offers many of the same features as the Flip, save for the front flap and multi-purpose pocket; it also eschews the magnetic closure system for a snap closure strap. It is also available in four colors and runs $60. Finally, the Corsa Designer Case is a slim, sleeve-style leather case featuring a perforated leather strip on the front, velvet lining, speaker opening, and a pull strap for easy removal of the device. It is available in five color combinations and sells for $40.
