iPhone web application developer, Comoki, has unveiled a new, iPhone-compatible Wikipedia interface. It's not alone, of course, but joins the ranks of web applications like iPodia with some nice interface improvements. It has a more reliable "Save" feature and makes some nice formatting decisions on the page, including making bulleted lists collapsible. It also makes use of a little Ajax for zooming images without reloading the page, which you may or may not prefer to the more traditional approach.

way the printed text didn't. For me, it was a breakthrough in how I was using computers to access content in a
different way. The CD-ROM was accessible with hyper-links to other content on the disc which is notable because before
the World Wide Web, hyper-links were really only being used in content like this Shakespeare CD-ROM (and in HyperStudio
and HyperCard projects). It was my experience with this CD-ROM and gophering into the University of Minnesota's system
to study 1990 Census data that opened my eyes to the coming World Wide Web explosion.
