Definately just phone David Urch and say something like "I have been in contact with Karl Borges and he said you will deal with it and get my replacement as soon as possible." Just be really nice about it and hopefully get a replacement by end of week or next couple of days would be really nice!. I think the pre-ordering stuff has calmed down a bit now. They should have "spare" n900s to post out. BTW say that Karl "asked me to contact him and let him know how I got on" - nothing wrong with a bit of peer pressure! You must get that n900 - you need it! It just freaks me out when I use the terminal and type "uname -r" !!!! Good Luck - will keep fingers (and other things) crossed for you!
