Android (Rooted): CyanogenMod, our favorite Android ROM, just released a new version that's rock solid on virtually every supported device, and brings the latest features in Jelly Bean (4.2) to Android phones and tablets that have been abandoned by their carrier or manufacturer.
If you're not familiar with CyanogenMod, it's one of the most rock solid and widely supported Android ROMs available. Aside from being our favorite, it's packed with features and customization options. Rooting your phone and installing CyanogenMod in place of whatever stock or carrier-tweaked version of Android you already have can offer you a way to update an old device or get new features that your current OS doesn't have.
CyanogenMod 10.1 has been in "release candidate" stage for a while now, which means it's been stable enough to work on supported devices. This update moves it to the stable category, meaning you shouldn't have any day-to-day issues with the build. Going forward, developers will focus on adding new features, like the upcoming "privacy guard," (aka incognito mode for apps), among others.
The new build rolled out last night, and should be available for all supported devices now, including phones and tablets like the ASUS Transformer, the Samsung Nexus S, the LG Nexus 4, the Galaxy Tab and Galaxy Tab 2, the HTC One X, and more. You can check to see if your device is supported here before you download.
