While it's not exactly blackberry-alike, a hopefully soon-to-be-released option is the clicks communicator[0] phone. I just ordered their bluetooth keyboard attachment for androids/iphones with magsafe backs, but if it's any good, I may shell out for their phone as well.
I was also a backer for the Mecha Comet[1] earlier in the year, which I'm hopeful about, although that's a couple of steps away from a daily driver phone at this stage, I guess.
I never owned a blackberry, but for me, the ultimate winner would be for someone to copy or licence the layout and form of the dopod838pro[2] (a.k.a. HTC Hermes 100) and pop some newer internals in it... If I had 100 million dollars, that's what I'd be doing...
