I’m a big fan of the cyanogenmod alternate firmware. It has allowed me to enjoy the latest versions of Android (Froyo!) on the original HTC G1. One of the most notable limitations of this device vs. almost all of the others is the amount of RAM available. The G1 has 192MB of RAM, of which only 95MB is available for programs under CM 6.0. Recently there has been a hack “EzRAM” which enables an additional 15MB of RAM for a total of 110MB. This additional RAM really makes a difference in performance.
