Help with Tethering

[jit]

I've been messing around on my phone and installed the tethering hack .cab file and deleted the appropriate registry key. Instead of saying having the options for Phone as Modem and Sprint under the Internet Sharing program, it only has Data and Phone as Modem.

Is "Data" the same connection as "Sprint"? Will I be charged for using that connection?

Also, the bluetooth connection does not work...my computer says the connection with the bluetooth device failed. Can anyone help me with this?

Thanks
