On my playbook when I scroll down the list of email messages and get to a certain point it just downloads more older messages from the phone. If this isn't happening on your playbook, then you should try rebridging the devices. Go to the bluetooth connections screens on both the phone and the playbook and delete the other device from the device list. Then go to the BB bridge app and reconnect them. Hopefully that works.
