Nope, not a stupid question, just empty because whoever has looked at this thread does not know the true answer.
Like myself for instance. I don't know the answer to your question about using a vodaphone on AT&T, if you are unable to get your answer soon enough, maybe try calling AT&T and asking them?
Also as for the differences, have you looked at the spec sheets for them? It may list there the differences. I have found that many of the differences between the 7100x series blackberry's are mainly the form factors.
