Upgrade Acer Iconia A700 to Android 4.1 Jelly Bean via CyanogenMod

The Acer Iconia Tab A700's high-res screen sharpens text and graphics to near-iPad Retina levels. Also, it's comfortable to hold and includes both Micro-HDMI and microSD.But the base version of the Tegra 3 can't keep up with the high-res display, resulting in frequent hangs and stutters while navigating. The cameras are unimpressive.The Acer Iconia Tab A700 overreaches with its high-res screen and is ultimately outclassed by tablets that offer better experiences for the money.
