I used pocketmac until Leopard came out. Leopard broke it and I noticed Missing Sync had an update before I saw one for Pocketmac. Missing Sync has worked for me since.

I also have 1 PC laptop (actually I have 3 counting the kids but all theirs have Ubuntu Linux on them) that I keep around just to load my GPS software and update my BB software. Since I have an 8320, I haven't had to do that in awhile :/
