Bluetooth Tethering in Linux on Credo Mobile?

[oiad]

Does anyone have/know what I need to have inside my ppp files for credo mobile? I have seen a lot of walkthroughs for all of the other major carriers but nothing for Credo. I know that they lease their service through Sprint, but I don't know if everything would be the same as a Sprint phone.

Any help is greatly appreciated. Thanks.

EDIT: After some more research I have found that Sprint may be blocking the tethering feature completely now. Does anyone know if this is true? Also I read that the Tether for Blackberry (sold on this site) uses their own servers, which works around the block. If this is true, has anyone been able to get it running in linux, or know of an application with its own servers like this?
