BigHand has announced a new software offering that allows you to dictate and then upload voice files from your BlackBerry for later transcription. I know a few doctors and lawyers that will be glad to hear of this new service since voice dictation has always been one of the things missing on BlackBerry devices. There is not specific mention of pricing but they ask that you contact them to get a pricing chart. If the prices are reasonable I think that BigHand may have a nice service offering for mobile professionals.
