Thank you jhend from whirlpool for the python script.
Telstra 4g Device (lsusb):
0f3d:68aa Airprime, Incorporated
Have to upgrade kernel sierra wireless modules, compile these drivers
Sierra update
I'm using Linux kernel 2.6.38-13 on Linux Mint 11
Download drivers for your kernel
http://www.sierrawireless.com/resources/support/drivers/linux/v3.2_1740_kernel-2.6.38.directIP.tar
Make dir and untar
mkdir sierra tar xvf v3.2*tar
UNPLUG device
Compile
make sudo make install
Check the sim card, there is a difference between bigpond & telstra sims Ref: http://forums.whirlpool.net.au/archive/1870382

Run with profile 2 for bigpond (Angelo's SIM) or 3 for Telstra sim
sudo bin/sierraconnect 2
Tried these commands:
sudo dhclient -r sudo dhclient -nw wwan0
Should have a solid blue & green light on device (4G)
Procedure after reboot.
gksudo bin/sierraoff
gksudo bin/sierraon gksudo bin/sierraconnect 2
gksudo dhclient -nw wwan0
Job done!
This should be in a easy to use GUI, better still this should work within network manager!
Here is the startup script I use and stored in /home/<user>/bin
#!/bin/sh sudo /home/angelo/bin/sierraoff sleep 2 sudo dhclient -r wwan0 sudo dhclient -nw wwan0 sleep 2 # Run the first time to turn on the modem sudo /home/angelo/bin/sierraon sleep 5 # Run a second time to start the connection sudo /home/angelo/bin/sierraconnect 2 sleep 5 zenity --info --text="Connection established"
I then made a link to this script on the users desktop with the following command
gksudo /home/<user>/bin/connect_4g
