Experiment with Alternate ROMs

Only the curious need apply here, but it's a fun place to be. Due to the open-source nature of the Android operating system, lots of {alternative ROMs} have been released for various devices. The most prolific of these is the Cyanogenmod project. The Cyanogenmod folks have released ROMs for just about any Android device released to date. The Cyanogenmod project aims to release a basic, no-frills, yet stable Android product, unlike some versions of Android that device makers ship.
