A frequent question about the refresh on Windows Mobile 2003, called Second Edition is "What about landscape, will my device support it?".
But the window to the Internet on any mobile device is its web browser. And it's no different with Windows Mobile 2003. Users frequently complain of compatibility issues between Pocket Internet Explorer and more recent Internet standards.
I was told by a Microsoft source that Pocket Internet Explorer does support the high resolution screens (VGA) perfectly now. Pocket Internet Explorer was completely re-architected around xHTML. The browser now supports One Column View exactly like you might have seen in Windows Mobile Smartphone 2003 devices in the market.
Some of the new architecture and features include XHTML basic, Cascading Style Sheets (mobile profile) and URL Mapper with UI.
Additional standard (among others) include: More HTML 4.0, Jscript v5.5, WAP 2.0 (WAP 1.2.1 + XHTML), WTLS, GDI+ Imaging, Animated GIFS and IPv6.
