[clug] Virgin Mobile Broadband with Linux Huawei E220

[Grant Morphett]

In a similar vein I have just got broadband working on my HTC p3600i using
Internet Sharing with a 3 Xseries plan.  I am connecting to the phone via
USB.  After much surfing and experimenting I found these very simple
instructions and it just works.  Very happy.

All of them discuss exactly the same way to do it but the different comments
of users experiences at the end may help you diagnose any issues you may
experience.
