So Ive been trying a bunch of different things to get pdanet to work over bluetooth with my windows 7 ultimate 64 bit pc. No matter what I tried I get error#633. I wound up deleting the device and connection . When I re- paired it with my pc I right clicked it and went to services. When I check off DUN and select standard modem(com5) instead of pdanet modem(com7) it connects using #777. When I try to select pdanet modem it fails with error 633. I can connect using the standard modem over bluetooth and have full internet access but I im worried that I will be charged for tethering by VZW since I dont have a tethering plan -- any way I can tell for sure ? pdanet on the phone says its connected but I dont want to get hit with a big bill.
