I have not had any problems with my igo keyboard connecting with OS2008.
I open the control panel and tap bluetooth keyboard. Open you igo keyboard amd presscontrol and both function keys to seegreen flashing light.
Tap 'pair' on the n800 and it will search and hopefully find your keyboard and select it. you will see a code 'four digits'
hold the blue function key and type these numbers, tap ok on nokia and press enter on keyboard
This should get you connected.
