[ROM] [AOSP] MMuzzy's Jelly Bean 4.2 - JOP40C - xda-developers.
Part of my day yesterday was spent upgrading my backup phone, the Galaxy Nexus, to the latest, greatest Jelly Bean port, version 4.2. In addition to being silky smooth and fast, there are some nice new features in this phone. My favorite is the the ability to bring up the most used settings tweaks by using two fingers to pull down on the notifications bar. You will need a rooted, unlocked phone to install this ROM; but, I am now wishing it becomes available for my Galaxy S3. SWMBO uses a Nexus as a daily driver; but, I will need to muster the courage to steal it long enough to update it. If I brick it, you probably won't be hearing from me again. If it works, I will be back tomorrow. Pray for me.
