Check out the new range of Tech21 Impactology cases for the new Samsung GALAXY S4. What is interesting is the protective nature of the cases. They are available now at T-Mobile stores across the U.S.

The casing features D30 Impact Material that protects the phone. Check out the technology in this video.
There are other cases too (Note: I was provided the pricing but I have some doubts over them when I compare them with their online store. Will verify again).
Impact Snap – Black, White or Purple
Impact Snap with Cover – Black or Pink
Impact Mesh – Smokey or Dark Blue
and
Impact Maze – Pink or Clear
