From the CTIA conference comes a preview of the Windows Mobile 6.1 IE6 Beta Demo. The new browser features zooming in and out, panning, and support for Flash - a first for phones. This video shows the new Internet Explorer being demo'ed at the conference while its new features are explained.
After watching that, I browsed through the related videos, and found this video - an extended hands-on demo of the new version of Windows Mobile, which shows the new "today" screen, the "getting started" wizards, the transfer music option, text messages, settings, and pretty much all the other features, too. Good stuff!
