Apple has just released version 1.1 of their iTunes Movie Trailers App, which means that it’s “now designed for the spectacular Retina display on the all new iPad.” The trailers app still has all of the newest HD clips from upcoming films, and now you can enjoy them on your awesome new Retina display.

The new iPad features a 2048 x 1536 resolution, which amounts to 3.1 million pixels on the 9.7-inch screen. According to Apple, it’s about four times as many pixels as the iPad 2, and more than many HDTVs. Many big-time apps are beginning to update specifically to accomodate the new Retina display. Just yesterday, Netflix’s app was updated to include optimized icons and images. They also announced that HD video was on the way at some point.

App developers are going to have to make these adjustments, as the early numbers suggest that Apple has another hit on their hands. In its first four days on the market, Apple sold three million new iPads. Yesterday we learned that the new iPad already accounts for 6% of all web traffic coming from iPads.

Today, the new iPad is coming to 25 new countries, including many in Europe like Austria, Greece, Hungary, and Italy – as well as Mexico and New Zealand.
