Few people browse Internet pages on a mobile device with a three inch screen. A few sites have pages that are optimized for a mobile device but they’re pretty hard to come by. (The iPhone does better with its ability to zoom in and out on a page but it’s still difficult to make sense of most web sites.)
If you’ve got a Windows Mobile-based phone, try going to Microsoft’s “Windows Live Search for Windows Mobile” at http://wls.live.com. You’ll install a small program and get a surprisingly useful collection of online tools for the city you entered. There are maps and driving directions, searchable lists of theaters and restaurants and other businesses, weather, and a few more things, all designed for the small screen.
