Trouble Tethering PAM to Mac OSX - BT drops after 10sec in Internet Sharing

[brokestudent12]

Ok well I'm trying to use tethering by either USB or BT in Internet Sharing and I'm on Sprint.
I have the registry hack, tethering works fine on any PC, I'm having trouble tethering to my Mac running OSX 10.5.6.

Yes, WMWifimodem works and so does USB Modem but they are both pay programs and I don't want to pay for something when Internet SHaring should be working, and I would like to get IS working for tethering to my Macbook.

When I connect IS PAM through BT my connection drops every 5-15sec.

Has anyone successfully connected their HTC TP to OSX w/o the use of WMWFM or USBM?

Thanks in advance.
