As you can see on the Spec cases the camera whole is larger on one than the other, i think this is because of the new senor and optics they put on the 4S, so look at the back of your cases before you buy because you could get one that covers up the senor which could result in not getting the full effect of the 8mp camera. Also look at these screen protectors, the proximity sensor cut out is more open on one....hmm why did they do this? they both say for iphone 4 same as the cases but im thinking these are the for the 4S....what do you think?
