Pocket Internet Explorer
The Microsoft® Pocket Internet Explorer is a full-featured Internet browser, optimized for devices with small, vertically oriented displays and for cached or customized content. HTML functionality is equivalent to that of Microsoft Internet Explorer version 3.2, with support for tables, forms, and frames. A fit-to-screen option dynamically resizes Web pages to maximize viewing on handheld devices without requiring the user to scroll across a page. A Zoom menu option allows the user to view text on the screen in different sizes.
Automatic state-detection determines whether the device is connected to the Internet and, if not, diverts the browser to a cached version of the Web page. On Microsoft® Windows® CE .NET-based devices that include Microsoft ActiveSync®, users can update their cached Web pages automatically by designating a Web page displayed on their desktop machine as a Mobile Favorite. Then, whenever the mobile device is synchronized to the desktop machine, the current version of that page is downloaded to Pocket Internet Explorer.
