I would try:

Building iPhone Apps with HTML, CSS, and JavaScript: Making App Store Apps Without Objective-C or Cocoa [Paperback]

Despite its title, it was the perfect book for learning to make apps for the mobile platform. I was surprised at how much I learned and was easily able to apply instantly.

Hope it helps.
