Spent the last two months immersed in HTML5 and iOS. At work we built a slick iOS port of a few of the sections from www.vw.com.
In the beginning it was meant to be a straight web-app, but as the requirements became clearer, we realized that we couldn't rely on the network. We would have to pull all of the data and make a native app.
As part of the project, I had to write up an HTML/JS version of the iOS picker. I'll post that next.
