The instructions should be online *Ferino". My Dad bought a Kindle Touch recently needed help registering it. When I did all the instructions just appeared on his Kindle, but if you search Amazon Fire Instrucktions Uk they should come up. Amazon customer services are usually very helpful if you are still struggling.
As for making it more like the kindle3. Don't know on that one sorry, hopefully someone will be along soon to help
I got one for my birthday! I'm a bit clueless - where do you find the instructions?! It is backlit, yes. I've been wondering if there's a way to make it more like the original kindle (ie 'matt' like a page) for when I'm reading in sunlight. Anybody know?! I'm excited to know I can MN on it!
