Hullo all,
Since there seems to be a general lack of English info about quirks & hidden features in the V2/V3 hardware, I thought I'd summarise some of them (that I found here on the forums, & through my own use) & put them in a wiki page.
You can find them at the top of this page -

Feel free to copy them to the MobileRead wiki if you want
