As should be expected by now, all three ROMs have their issues. Very few Jelly Bean ports are fully functional, but the AOKP builds have about as much working as the CM10 builds at this point. So while they may not be daily driver for most, they are definitely something to try out and have fun with. XDA Recognized Contributor Mazda, along with the rest of Team DIRT, are responsible for bringing the unofficial AOKP to the EVO 4G. They are also the ones who brought unofficial CM10 to the EVO 4G. The AT&T Skyrocket build comes from XDA Senior Member armyveterangunner29 with some help, and the AT&T Galaxy Note build comes from XDA Senior Member JamieD81.
In the list of things not working, all three ROMs cite that they have similar issues to CM10 builds on the same devices. This includes some hiccups in Google Now functionality, camera issues, some video codec issues, and other bugs. These bugs are expected to go away in later releases, so if you’re looking for something more solid, all you need to do is wait.
