I've got the Arnova 7b G3. It arrived yesterday. From settings I can find the model number, the Android version 2.3.1, Kernal version 188.8.131.52 and build number. My question Ladies & Gentlemen is; Arnova advise to update the Firmware, how is this done? I can't find what Firmware version is installed so how is this done also? Is there a Proper User Manual about? The little user guide that comes in the box is hopeless!
