Microsoft released its first beta version of Deepfish last week. Deepfish is a web browser for mobile devices running Windows Mobile.

What I have seen so far from Deepfish is nothing better than what Nokia has already on the start since quite a while (2005!) with their S60 web browser. I use it every day on my Nokia N80 and it works great.
Laptop Mag has tested the Deepfish browser. Their take: "Although it's still in beta, our first tests of the product left us interested in the new Web-browsing tool but unsure of its mobile readiness or need. Microsoft considers it a prototype and has not announced any plans to offer full or more widely available versions."
