Please read this post if you're concerned about any of the limitations of BIS 2.0 as compared to BIS 1.8.
I've read your post- don't you think you are overreacting?
OK, put it another way: in democracy, majority decides. In business, majority of customers decides.
If you have not seen major outcry from users on T-Mobile, Verizon, Sprint and Nextel about what you call BIS 2.0 limitations- the writings are on the wall: Cingular is going BIS 2.0, sooner or later.
Otherwise, Cingular will be losing blackberry customers to other mobile carriers offering no quota blackberry mailbox, instant Yahoo email on blackberry, and other new features.
What do you think?
