Just bought a Viewsonic g-Tablet (1.2-4349) so I can test an app I'm developing. Hit a brick wall, as there is no tick-box option in Settings / Applications named "Unknown sources". This is pretty much a standard Android OS option that allows you to load apps not from the market on the device. I even installed a new ROM today (Mountain Laurel) thinking that might somehow show the setting the stock ROM was not; but no joy... still not available. Is there a way to get this setting to be displayed/set on the device, or should I try to return it and just get a Samsung Galaxy? Thanks, G.
