I haven't tried a blackberry, but I have tried Windows mobile device thumbboards - and accuracy may be ok, but thumbs only on such a small keyboard ... it's just not good enough to be even a netbook keyboard replacement. Too tiring, too difficult/slow to access other keys/symbols/numbers...
I like the ideas of the senseboard ( http://www.senseboard.com/product.php ) and the dataegg ( http://www.xaphoon.com/dataegg/ ) chording keyboard best. Unfortunately senseboard seems a bit of a dead / vapourware company and the dataegg vanished and the closest thing I can find to it is the cykey ( http://www.bellaire.demon.co.uk/index.html ) which I have tried, but it's not a keyboard replacement really. Apart from speed, it needs to be on a surface and metakeys are awkward.
Twiddler I've seen online but it looks incredibly uncomfortable in a finger-contortion sense to me.
Imagine a DataEgg style jacket for the iPod/Phone...
