7) I don't have a warranty on my hero, which bothers me the more I think about it, since I bought it on ebay. If I got the N900, I would have a 1 year warranty, is it possible to extend that?
NO. not on ebay especially. Not sure but I think you can if you buy it through an operator with an option for extended warranty. Or at least in Australia you can


cant get extended warranty for the N900 in AU, I wish
that would mean its available here
