What is the difference between the Commuter Series and the Commuter TL Series for iPhone?
The polycarbonate shell on the Commuter Series case wraps around all four sides of the device making the case a bit sturdier. The polycarbonate shell on the Commuter TL Series wraps only from top to bottom along the spine of the device but also offers inner coring along the sides of the silicone layer to ensure device protection.
