My phone has had this problem. It has not been dropped or subject to any excessive force. mobicity, Australia, provided me with the photo (attached) after refusing to honour their warranty.
Thank you Texrat. Thank you Nokia. Thank you Nokia Flagship NYC. I brought my 2 month old N900 into the flagship store today, as I posted earlier I would. They replaced mine! I think it was an exception the guys made, but they have gained a customer for life. N95-1,N95-3,N95-4,E51,E71-2,N810,N96 and now N900. This is the reason why I spend more than $500 on Nokia every year.
