It looks like Version C is missing only LTE-Band 20 (Europe, I live in Germany) to be useful in Europe as well as in USA and Asia. I'm travelling a lot worldwide and if it would be possible to add Band 20 into Version C, then Version A (Europe) would be obsolete since all other supported bands of Version A are already in Version C. This would give you a strong advantage over your competitors, and I'm sure that I'm not the only one who would greatly appriciate this (make Versions A = C incl. Band 20) in one of the next updates.
