Tested with upstream v3.3-rc5 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc5-precise/) and the device still not detected.
I can confirm that the updated drivers from Sierra Wireless website work on v3.3-rc5. After installing the updated drivers, the device is detected and a wwan0 interface is created.
