Hey Stanjse, I did the 'upgrade' yesterday. I have an Asus eepad - there is a manual download available via Asus website, which you need to download onto a PC or Mac, unzip the file and save it at root level to an SD card, you then pop that into your tablet/pad and you should be able to use that file to upgrade your system...hope that helps? However I will just add that since I downloaded the 4.0.3 version I am unable to connect via vpn - I'm currently trying to find out if it's at all connected. Cheers, James.
