The booklet I have says M001 User Manual MID. That's the only manufacture info I can find I'm afraid. Nothing listed under the About section apart from Kernel info etc.
I found a few firmwares for it, both stock and custom and all of them are Android 1.6. Some of the forums I read said that the tablet does not have the hardware to run anything newer that that, so that would mean a new tablet to get beyond 1.6 from what I can tell.
