Lately, I have been looking into development for the mobile web. Fortunately I was offered the opportunity to host a mobile web workshop in Frankfurt on 28 + 29 Sept. 2011 as part of the Mobilism Workshops Series.
Mobilism workshops are a two-day affair where at least half of the time is spent in actually testing websites on mobile devices; including a few you've never even heard of. The other half of the time is taken up by PPK and Stephen Hay talking about various aspects of mobile web design and development.
So if you are interested and live in Germany, register for the workshop.
