Actually i do not know a way to do that. I havent ever came across a type of program like that.
Anyways, The Blackberry Crimson looks nice, but nothing really different from the pearl except the Qwerty keyboard. I would say if you wanted a Blackberry just get the Pearl. You wont be sorry. its a great phone. I just dont like how Blackberry makes you use their servers.
Another phone you can look into is the Samsung i320n. It seems like a good device for you. Qwerty, Slim, and has a 412mhz Intel processor, making it faster then both devices, which means Windows wont be slow.
All the devices are priced very similar. So pricing isnt a issue between the 3.
I have included a comparison of the 3 devices for your convience:

Actually the comparison is with the i320, not the i320n. They have essentially the same specs, its jus tthe i320n looks better in my opinion compared to the i320.
