Mac won't connect to network via bluetooth Internet Sharing

[macrolific]

I have the HTC Touch through Sprint, and I'm on a Mac. I'm trying to connect my Mac to the Internet by using Internet Sharing on the Touch. I've gotten very close, but I'm not there.

Based on some advice I found on the Web, I tweaked the Touch's registry such that the 2nd drop-down menu on the Internet Sharing application's page, Network Connection, is now being displayed. As per the Web site's instructions, I changed the dropdown Network Connection selection from Phone as Modem to Sprint PCS.

I now am able to start Internet Sharing on the Touch, select Connect to Network from the Mac's bluetooth menu, and all appears fine. Both devices say that the Mac is connected to the network. But the Mac has no IP address, and Safari says "You are not connected to the Internet."

I'm now lost, but I'm so close. Is there anything left to try in order to enable my Mac to connect via bluetooth to the Internet through the Touch's Internet Sharing?

Thanks, in advance, for all help.
