Android enthusiasts fiddling with custom ROMs are familiar with two major efforts, namely CyanogenMod (CM) and the Android Open Kang Project (AOKP). With the release of Jelly Bean, CM beat AOKP to the punch in terms of launching an official build based on Google’s latest Android release.

While nightly builds of AOKP already implement a custom 4.1 Jelly Bean release, official releases of the custom ROM are still based on 4.0 Ice Cream Sandwich. AOKP developers, however, are nearly ready with a formal release: AOKP build 1 r28 is already available for download. Device support is still limited, and the developers are not accepting bug reports yet.

Some of the highlighted features included in this build are as follows:

  • Notification Toggles
  • Lockscreen tweaks (no custom targets yet)
  • Navigation bar modifications
  • Custom kernel performance options
  • LED colors
  • Notification wallpapers
  • Phone ringer modifications (flip call to silent, silent/vibrate when headphones are in)

Head on to the source link for download and installation instructions. Again, device support is still limited, but the developers have confirmed these work for the Galaxy Nexus, Nexus S, Nexus 7, Galaxy Tab 2, T-Mobile Galaxy S2 and T-Mobile Galaxy S3.
