So, I put this ad up 2 weeks ago and held onto the unit for the buyer, who backed out. So it's back up for sale.
Same details as before, 3.5 months old, purchased on Dec 24 2009 and received on Dec 29 2009. Works perfectly although I lost the original stylus the next day. It has a new back cover from Nokia with the sticker still on it. Works perfectly, screen's gorgeous, nearly new, all that. Asking price is $425 plus shipping.
I'm adding in a belt holster case too. It's built for the Motorola Q but the N900 fits in it PERFECTLY, it's great. The clip rotates so you can have it vertical or sideways or angles in between! WHEE!
