I recently flashed to the Fresh 2.1.2 rom, and i'm having trouble using the "Wireless Tether". I've uninstalled the one that came with the rom, and i've installed a fresh new copy from the Marketplace. But every time I've tried hitting the "tether" button, it says "Unable to start tethering, please try again!" My superuser app isn't doing anything, this might be the problem. Whenever I open the superuser app, it's a complete blank screen.
