Just when you thought the HTC Evo 4G has been left behind in development, XDA Developers member jmztaylor has compiled CyanogenMod 10, based on Android 4.1.1 Jelly Bean, for the said phone.
Jelly Bean comes with triple buffering interface, a smarter keyboard, faster response in switching between previous apps, new navigation menu, and much more. In addition to all the new features that Jelly Bean has to offer, CyanogenMod 10 has its own add-ons for better performance and great customization on your HTC Evo 4G.
CyanogenMod 10 for the Evo 4G is still in a very early stage of development and is not yet suited for daily use. In fact, the ROM is still best considered a preview build. According to the dev's notes, Wi-Fi, sound, phone calling, data, and SMS work, but the camera, camcorder, 4G data, and front-facing camera don't work yet.
