DM 4.6 is by far the most stable a crucial_xtreme suggests and I woul suggest that you get the version without media manager as the Roxio product inclusded is moderately horrible and slows down your PC.
I agree with Pete6, no media manager. Some people use it and probably like it, I rather avoid it and use my Blackberry as a flash drive and copy over all my files myself. I never have been a fan of Roxio products.
DM4.6 is the most stable and will easily allow you to put a newer OS than released by your carrier on your berry, 4.7 will not (easily). Roxio is a useless conduit for putting your media on your berry. You can cut and paste to your SD card much easier or use media sync from itunes.
