I use the built-in mail and address book with Snow Leopard and have it all sync to my google account, which in turn syncs with my palm pre. It's great to some extent, but I've recently run into a problem. I just had to add about 50 contacts for a school group and I have no desire to have all of them end up on my phone. I can't delete them from the phone without losing them on the other accounts. Any ideas? I can't seem to find a setting to only sync certain contacts.
