Confirmed fix is now in Intrepid. Just upgraded my laptop today to make my own network manager with the fix. But it appears the fix is already there and there is a new auto connect (nice touch).

As for ttyUSB2 it looks like you can issue commands to the card while ttyUSB0 is has the data connection.
Here is a quoted from sierra's site:
http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=1076

"If you are using the AC881, MC8781, MC8780 issue AT commands or queries to /dev/ttyUSB0. AT commands can be used while a data connection is established on /dev/ttyUSB2."
