Earlier today, Ricardo Cerqueira (aka RC of the CM team) posted on Google+, teasing that a CM9 build for LG's Optimus 2x (P990) would be available soon. For some time now, the CM team has been keeping a spreadsheet on Google Docs, tracking the P990 build's progress, which indicates that, as of 2/9, ICS for the Optimus 2x is all but fully functional, carrying only "partial" functionality for the phone's camera and video playback capabilities.
About an hour ago, RC followed up with another post, linking users to download mirrors of the first CM9 builds for both LG's Optimus 2x and G2x (P999).
As usual, RC advises users that any issues with the builds are known (so there's no need to report them), and goes on to warn that the builds are not supported, meaning updates may or may not come in the future.
Those interested can find the matching kernel source at CM's github. The builds' full source will be available there within about a week.
Without further ado, head over to RC's Google+ post to grab the downloads, and let your Optimus 2x or G2x enjoy some ICS goodness.
Thanks, Péter Teleki!
