Back during the summer, I talked a bit about a new case from Ballistic Cases for the iPhone 4 called the Ballistic HC. Ballistic Cases is now back with another cool case for the iPhone 4 called the Ballistic SG that has three layers of protection and looks pretty cool to boot.
The case has an outer layer of soft TPU to help absorb shock when dropped. A second layer of impact resistant polycarbonate is integrated into the design and then the third layer is another shock absorbing line of protection as well.
That third layer is a soft silicone material and the corners of the case are reinforced in case the iPhone 4 lands on the corner. The case comes in solid black or black and red colors as seen here. The case isn't shipping just yet, but it will be in AT&T stores for $29.99.
