I have tried this over and over. No luck. I get the the window where it says "pairing." I try to put the passkey in , but it never takes. By looking at the keyboard, I assume that you hold the FN key down and then hit the corresponding number keys, right? I have also noticed that the flashing green led stops flashing when the n800 is pairing. If I cancel the pairing, the light starts flashing again. I am running the new 2008os and the keyboard is a xtbt01. Any help would be appreciated. BTW I second the comments in other threads about the nasty sticker across the keys. If I could get my hands on the bozo who came up with that idea....
