XyloT3 (2.0) Touch-Thru© case by ivyskin is the first of its kind to provide a hard screen shell over the iPhone 3G/3GS. This German designed material is second to none on the market today! The 2.0 is the second version of the XyloT3 with updated snap-on mechanism for better grip and performance. The sliding back piece has been replaced with a snap on upgrade for better fit and protection. Now the best iPhone 3G/3GS case is even better.
