No, no, no, no, no, no. I didn't mean the actual camera hump would change, I meant that the taper around the camera hump in the newer mods is oblong in shape. Look at the two attached pictures. You can see that the new JBL is obviously oblong in shape, whereas the old one obviously is round. This seems consistent with the fact that if there are two cameras positioned further apart, then the taper would need to widen too so the cameras don't "see" the edge of the mod.
I have no doubt that the new mod will work on the old phone, but the camera results may be undesirable, that's all. There's a reason they made that oblong on the new JBL.
I've also attached a sketch to hopefully illustrate the differences.

Thanks for the clarification.
