This tutorial will take you every step of the way through installing CyanogenMod 4.1.99 on your G1 phone – the first “legal” version of CyanogenMod (after Google sent cyanogen a cease and desist).
The steps outlined in this tutorial were gathered from the official announcement of 4.1.99 on the xda-developers forum. For more information on 4.1.99, see this thread.
