It has just been a few weeks since Google released Android 4.3 Jelly Bean, but the CyanogenMod team has already started rolling out CyanogenMod 10.2 which is based on the latest version of Android for select devices.The CM 10.2 update is currently available only for nine Samsung devices and the team has not listed the number of devices which will receive the update, nor have they shared a timetable on its roll-out for other handsets yet.
The supported handsets are the Samsung Galaxy S III for Verizon, AT&T, Sprint, T-Mobile, Cricket, Metro PCS, and U.S. Cellular. Also on the list are the Samsung Captivate and the Samsung Relay 4G.
The list is bound to continue growing, so please check back on the download page regularly as the team continues to add more devices to their CyanogenMod Downloads page.
You will also be required to download the GApps 4.3 pack to run the latest version of CM 10.2 on your device.
