CyanogenMod is a pretty big deal in the Android modding world, and there's a good reason for that: it's fast, lean, well-featured, and supports a ton of devices that manufacturers have abandoned. When Android 4.0 was released, the CM team made it clear that CM9 (based on ICS) would be a long time in the making, as they were going to focus on doing everything properly and cleaning up the code. And now, as promised yesterday, CM9 stable is rolling out en masse.

So far, the supported devices:

LG Nitro HD/Optimus LTE

Samsung Galaxy Tabs

Samsung Galaxy Note (Intl)

Samsung Galaxy Nexus (GSM/CDMA)

Sony Ericson Xperia Mini Pro

Samsung Galaxy S II (Intl/AT&T/GSM)

Sony Ericson Xperia Neo

Samsung Galaxy S

Samsung Epic 4G

LG Optimus Sol

Samsung Nexus S (+/- 4G)

Sony Ericson Xperia Arc

Sony Ericson Live With Walkman

Clearly the list so far is dominated by Samsung and Sony Ericson, but builds are still going up every 20 minutes or so - the build bot is just churnin' them out.

As mentioned in the CM9 announcement post, the team will be moving on to CM10 (a process they promise will be much quicker). The only development that will be done for CM9 will be critical bug fixes.
