Ok this is a dumb question, I got a cheapo off brand chinese tablet running on Froyo, which the build in system update seems to be disabled, it keep saying it is up today, but I saw the same device with different brand name running on Gingerbread, so my question is how do I update mine, as I am sure I can get no support at all from the supplier. I don't want to root it yet, until I know a bit more about the OS, thanks for your help !
