If you're not sure if you have a Gen 8 tablet, this update applies to the Android tablets released last year by Archos, the model numbers are 28, 32, 43, 70, 101. I don't think this includes the Arnova tablet, ereaders, or netbook that Archos have shipped.
Just out of curiosity, is anyone using the original firmware? I thought most of the Archos tablets had custom firmwares. Is that true?
