HTC announced the HTC HD Mini just a few weeks ago at the 2010 Mobile World Congress and it is now surfacing on Amazon.com's UK site. The listing is for pre-orders of the Windows Phone at a price of 369 pounds (about $556US). The listing indicates the HD Mini is due to be released on April 14, 2010.
As an added bonus, if you happen to live in the United Kingdom, Amazon is also throwing in free shipping. Still no indication on whether or not the HD Mini will head across the pond to U.S. Markets.
