The first trickle of the CM9 ICS builds is starting to flow. Ricardo Cerqueira, RC of the CM team, just put the first CM9 builds for the LG Optimus 2X(P990) and G2x(P999) available for download. They are not 100% functional, but are very close. The known issues are "partial" functionality for the phone's camera and video playback functions. If you have the aforementioned phones and want to give this CyanogenMod version of Ice Cream Sandwich a try, feel free to hit up the download links below. For more info you can check out the Google+ source link below.
Even though these are incomplete betas, the only issues are known issues, so there is no need to report anything to the developer.
