Torch Mobile, the makers behind the Iris Browser, updated the WebKit-based Windows Mobile browser. The new browser, which is up to version 1.1.5 now, offers a number of improvements, according to WMPowerUser, including:

-Noticeably faster scrolling

-Up to 25% improvement in page load time

-Improvements to text input

-Rendering and layout improvements

Looks like it even has a cover-flow interface for webpages.

You can download the new version from Torch Mobile.
