As much usage as you can get out of a properly modded V3, the processor can only handle so much data at once. The problem may simply be in the data capabilities of the 'non-smartphones' as opposed to anything that can be done on the BB users end. The input simply overwhelms the processor. If your freind is a Moto modder, he may be able to do something about streamlining the data input, but, other than that I dont expect any real solution. Since I never encountered that issue, I couldnt tell him where to begin.
