Speck Products has announced its upcoming ToughSkin and SeeThru cases for the iPhone 3G. Originally announced in The Free iPod + iPhone Book 4, the ToughSkin for iPhone 3G is a rubberized case offering a textured pattern that protects the iPhone from accidental bumps and drops while allowing full access to buttons and controls.

The SeeThru for iPhone 3G is a hard shell case with built-in rubberized side strips for extra grip and a specially designed bottom that slides off for docking and conveniently doubles as a stand.
