I picked up a Mark IV and the Ting 958u this week. I have a Mark I but didn't have the free time to upgrade it and it looked like the Mark IV had new HW. When I saw Darren demo it and mention TING, it looked like he was using the Sierra 958u usb modem with it. Turns out the out of the box does not support that modem. Anybody got any idea how to get the 958u to boot the Mark IV for some portable man in the middle ? Thanks Fan since the Virginia days
