I use the RIM8320 and since the 10.5 install have been unable to sync using Pocketmac. Tried everything several times, for months. I was very reluctant to PAY for MS for BB, especially based on the horrible reviews found here. But finally out of frustration I paid and am kicking myself for not trying earlier. The fact that there is no trial really bothered me.

But MS does work--it synced both the 8100 and 8320 the first time, flawlessly. And have been doing so for over a week. I sync contacts, cal, and tasks only.

The one thing I did try the FIRST time is overwrite device. I think helped prevent any dupes.

Give it a shot, it works very well.

I have been using VDP for almost three full years and I'd reco it to anybody. It may not be as glitzy as a few other notepads, but its functionality is excellent. Early on Gus gave me some guidance on some custom scripting that save me dozens of hours. Great product, great support, great stability.
