Install CyanogenMod 9 AOSP ROM On Nexus S


The Nexus S gets it’s first taste of CM9, the ICS based AOSP ROM! ICS ports are all the rage right now, and the team at CyanogenMod went underground to work on their new CM9, thus keeping things a wee bit. Guess what? Koush, the guy who made ClockworkMod recovery and ROM Manager possible, is working on the CM9 project for the Nexus S, and he has released his build to the users for some early testing. The ROM, still in an Alpha stage, is said to be stable enough to be used as a daily driver. Apparently almost everything seems to be working just fine, and if a few bugs do exist, the ROM is in Alpha 11 of its stage, so bear with it if you do want to give it a go.
