Speck Products has announced two new cases for Apple’s fourth-generation (4G) iPod. The 4G SkinTight case, which will begin shipping on Aug. 31, is a rubberized skin that hugs the iPod to provide protection from bumps and scratches without adding bulk. It comes in three colors (frosted clear, blue and pink) and can be purchased individually for US$19.95 or as a 3-Pack for $29.95. The 4G iStyle features an all leather construction, a plastic screen shied, and a removable swivel belt-clip. It comes in black for $34.95 and will be shipping on Sept. 23.
