You've been told countless times, several times by me personally, that USB Host mode has actually been working for months, with just a bit of kernel tinkering (software). If you'd read the more interesting parts of that thread you'd see it mentioned there. What Year? I got my N900 in Febuary, people are still buying N900's now, you'll have to wait until Nokia actually stop selling the N900, then wait a year before you can be certain no one will void their warranty. Or are you just waiting for your warranty to expire before you perform these mods you've devised?
