The T-Mobile HD2 is a cool phone, It has a great screen and peppy processor, Windows Mobile actually runs pretty well with decent hardware. Its not locked down, you can multi task, play music and movies. Definitely a good deal if you have a 1st gen iPhone 2G 4GB or 8GB and want to make that switch. If they allow you to buy it off contract for $449 – $350, that’s a great deal. Anyway, i guess i just assumed when they said $50-$350 it would probably depend on the age of the phone. "Great new for Apple iPhone customers who want to purchase an HTC HD2 – from April 1 through May 19, customers can trade in their Apple iPhone and get up to a $350 credit when puchasing an HTC HD2 at participating T-Mobile Dealers, through 1-800-TMOBILE, or through a Business Direct Sales Repressenttative."
