I have tested for you a good version of Android Gingerbread 2.3.4 on my Rikomagic MK802II stick. The firmware is stable and runs very well all the basic apps. If you want to try this version, you cand download the firmware image file from here and use this video tutorial to upgrade it. Youtube app works just fine and the Skype audio and video quality is good. (I used my VX-800 Microsoft webcam). Antutu benchmark score on this firmware is 2.889 points, better than 2.683 obtained with the JellyBean 4.1 version.
