I've wondered this as well and AFAIK, no one else knows either. The local Verizon folks had no clue about the different sizes between the 2 outer cover materials. My "guess" is, will depend on the case - those with generous tolerance might work for both, those really tight may not. I'm going to just leave mine "as is" and use a generic pouch until the dust settles. FWIW, the ballistic nylon looks like it's built like a tank.The 2 bodies have 2 different thicknesses 10.6mm & 11.2. Does this mean 2 different cases or is the .6mm not relevant?
Yes, I'm a bit anal.
