DSHobro is a homebrew that lets you surf the web on your DS. It is based on a PC application that parses web pages, and sends the result to the DS. Version 0.1 alpha was released long ago, in april 07, but was just a tiny demo of the possibilities offered by the PC/DS mechanism. DSHobro 0.2 now takes full advantage of this mechanism and allows you to really surf the web, actually read text and view images (text is clear enough to be read) and so on.
