Since this should be in this thread not the N810 stuff anyways...

Are you talking about the N800 or the N810? (you've posted this in the N810 forums but mention the N800 so...?). If you're talking about the N800 it's easy, just make sure you've got OS 2008 installed and either grab one of the adapters mentioned here:

There's been a lengthy discussion about what devices are and are not supported in another thread, but the easiest thing to do is check the Wiki entry as it kind of sums things up:
