We sucsessfully just upgraded to BES 4, and now need to get our handhelds onto the 4.0 firmware. Unfortunately, I'm not 100% on which users have which models. I know we mostly have 7100t's. There are quite a few 7230's around. And I know there are a few straggler 5810's out there. Other than the few 7100 and 7230 units on 4.0, I can't tell what model BB they have. Is there anyway to tell via PIN? Or maybe an app I can run on the BES server that querries the handsets?
