Now the photos don’t really tell us how big the phone is, but it does show two different sizes, although they are said to be of the 4.7-inch and 5.7-inch variety, which contradicts earlier reports that the larger iPhone will be of the 5.5-inch size. Interestingly enough the cases also shows a couple of different cut outs for button placements.
As it stands the placement of the buttons on the iPhone have been pretty much standard from its early inception until today. However the photo shows additional cutouts in the top left corner of the phone, and the top right side profile of the phone. The case also shows the usual cutouts so it would suggest that not only will there be buttons moved about, but there could be new buttons added as well.
This seems to corroborate earlier claims by analyst Ming-Chi Kuo that the new iPhone could feature a moved power/sleep button. In any case the case manufacturer could simply be basing the design of the cases on rumors and leaks, as opposed to the actual dimensions since we doubt Apple would have shared with them the details at such an early date. Take it with a grain of salt for now, but if the rumors are true, which sized iPhone are you planning on getting?
