This brief tutorial will guide you through upgrading CyanogenMod 4.1.99 to 4.1.999 on your Android G1 phone.
Fortunately, the process to go from 4.1.99 to 4.1.999 is much, much easier than updating to 4.1.99 itself. For a full list of all the changes in v4.1.999 see the changelog. One of the bigger changes is that bluetooth is now 100% working. Please note: the steps outlined in this tutorial require that your G1 is currently running 4.1.99. You cannot use the method outlined below to go from any version other than 4.1.99 to 4.1.999. If you need help installing 4.1.99, please see this tutorial.
