and what i meant internally or externally is what do they call the OS versions in internal memos to each other? version what?
do they have teams of guys working on an OS for each model of phone at RIM? i doubt it...they have one OS and they created a hardware abstraction layer to interface between different hardware configurations...it's a layered OS design....
