Been lurking here for quite awhile but finally registered.
I work as an Avaya switch programmer but I also run our companies BES server with about 300 users right now. We use Exchange and our primary provider is T-Mobile.
I currently own pretty much every model BB since I troubleshoot them, my 8100 came in today so I retired my 8700g beside my 7105, 7100, and 7230.
Great forum that has helped me alot since I took over the BES with no experience.
