If you possess both a Nexus 10 and a predisposition for hacking your gadgets, you'll be pleased to hear that the first few nightly builds of CyanogenMod 10.1 for the Samsung-made Nexus tablet have started to appear.
Two early builds of the popular custom ROM are available on the official CyanogenMod download site at get.cm at the time of writing, weighing in at around 163MB.
It's still early days for CM10.1, which is based on the recently open-sourced Android 4.2 Jelly Bean. As such, you can probably expect a few bugs and incomplete or missing features in these initial nightly builds until things become a bit more stable.
Regardless, those with an OEM unlocked Nexus 10 and a healthy contempt for playing it safe can find download details at the source link below.
