Is there an easier way to get internet access?
With the last stable update cyanogen activated USB Tethering (Internet connection forwarding from the phone to e.g. a notebook).

To activate USB Tethering you need the CyanogenMod 4.2.3 and an USB cable.

Plug the cable into phone and computer, enable tethering via

Menu> Settings> Wireless> Internet tethering

A network interface called usb0 turns up. The connection is created automatically and you can start surfing right away.
