If you're using CyanogenMod and you've been lucky enough to get your hands on a Nexus 4, then you're in for a treat. The CyanogenMod team announced on Google Plus that they're rolling out the first Nexus 4 (mako) nightly build for CyanogenMod 10.1, which is based on Android 4.2. The team is doing this because they've seen Nexus users installing third party CyanogenMod 10.1 builds, so they thought they'd take advantage of the demand they've been seeing and begin releasing nightlies.
That's great for Nexus 4 owners, but those who picked up a Nexus 10 are also getting some good news of their own today. While CM10.1 nightlies for the Nexus 10 (manta) aren't quite ready to go yet, they will be soon. We'll have to wait until the CyanogenMod team dishes more details, but their Google Plus post makes it sound like nightlies for the Nexus 10 are right around the corner.
This makes the Nexus 4 and the Nexus 10 the first devices to get official nightlies to CyanogenMod 10.1. As for all of the other devices out there, it'll be a while longer before CyanogenMod 10.1 is ready to go. The team says that all other devices will continue getting CyanogenMod 10.0 builds until they "finish merging 4.2 and flip the switch for everybody." They unsurprisingly weren't interested in talking ETAs, and thanked users ahead of time for not asking.
Of course, we're thinking there are quite a few CyanogenMod users who don't have their Nexus 4 yet. The device sold out amazingly fast when it was released and only became available on the Google Play Store again yesterday. In any case, if you've got a Nexus 4 in-hand, you can grab the nightly build for CyanogenMod 10.1 right here.
