I’ve found a couple great resources for those interested in getting started with iOS development. The first is called iCode Blog which consists of a great collection of iPhone tutorials.
I think most developers would agree that one of the best ways to either learn new programming languages or to simply improve as a developer, is to read code and learn by example. Appsamuch is exactly that and has 31 example iPhone applications with the complete source code for each. In addition, each app comes with a nice step-by-step guide to get you up and running as quickly as possible.
