Nokia's rebate company just sent me a rejection letter claiming I did not send a receipt. Yeah... hm... I still have the receipt on my N900 when I took it to work to print and mail.

They're really looking for any excuse to not give out the $50. Luckily I got the $100 from Bing a few weeks ago. That was quick and painless (no paper, no hassle) compared to Nokia's draconian methods.
