A rumored 3G BB is in the works, the 9000 series, but when it is released is anyone's guess. Rumor has it sometime in 2008.

But, I don't think you can get that kind of speed on any handheld, BB or PPC. Too many variables such as the connection, the processor, memory, the distance to the tower, tower congestion, etc. Plus most websites are not optimized for mobile users.

If you feel you really need that speed, never leave your desk and PC. What do you do at night? Do you never sleep?
