I'm really beginning to think cardmgr is not so stable. I ended up rebooting the Z and now the network config has no problem seeing the socket bluetooth. Before I did this I hciconfig gave no info and dmesg said very little.
There were some other stuff that I did, but they are irrelevant now that it's set up. I'm now waiting for the phone to be activated and then it should be mobile surfing bliss (except in the subways).
