The tablet was already paired with the phone & I then connected them. After that ran the script bluetooth-pan-tethering.sh & that symbol came up. Then made sure the phone had a net connection.

That said I just got a different tablet the Samsung Tab 10.1 & I'm having trouble establishing that "Bluetooth Tethered" connection reliably. I hope it's not a hardware issue though it is working right now as I type this message.
