The CyanogenMod team has been slowly but surely rolling out CM 10.1 builds for various devices - mostly Samsung - over the last week or so. A handful of new tablets and phones hit just yesterday, including the LTE Galaxy Nexus variants, 3G Nexus 7, Galaxy S, SII, some SIII variants, and Galaxy Tab 2. Adding to that list, builds for the Verizon and Sprint variants just hit the scene this morning.
It could oftentimes be unstable and not properly tested, lacking any changelogs, but eventually evolving into alphas, betas, release candidates, and finally stable releases.
You can find both downloads on CM's official download site, and, as always, don't forget the GApps!
