Thanks Rob. Since I posted I filed a trouble ticket with pocketmac and they sent me two apps - one which wiped the 8700 (through pocketmac), the other which 'reset' my mac as if I'd never synced via pocketmac. They also reminded me to make sure I had the time zones matched.
And it worked! I'm now well synced b/t my mac and 8700. Now all I need is my unlock code and I'll be off and running with TMo
