Amazon is still in the gift-giving spirit, it seems: it is once again selling a great selection of smartphones for a penny.

The retailer ran a similar penny sale late last year; this time around, it is offering three Windows Phone 7 devices for a penny, to celebrate the release of the Kindle app on the handsets earlier this week. If that's not your thing, it's still worth checking out: other phones, including the HTC Incredible, are also being offered for the same great price.
