I have an orange and black one. Mine has a cover over the dock connector and the headphone jack.
No clue as to why yours doesn't have a cover over the headphone jack. That opening is pretty big too.
Hopefully yours doesn't have the almost impossible to open camera slide cover that mine does. The interior slider portion of the Bullfrogz isn't very secure on mine. Neither is the silicone. It comes loose when being pulled from my pocket.
Other than those minor things I actually really like the look and feel of that case even without an integrated screen protector. I still prefer my Survivor though. About the same size overall but it has an integrated screen protector, belt clip, is just better drop protection.
