What are all the documents i need to read to become a iPhone developer?

I knew C, Cpp, Java, Servlets, JSP and Objective C. Now, i want to do some web related application in iPhone. I have Mac system, XCode and all. Also i registered in developer.apple.com. My problem is, where can i start to learn about development?

S开发者_如何学JAVAo many documents are available in Apple's site. But in each document, they gave a lot of links for other documents and said "before reading this read this" I just hate it.

So please give me a clear way to learn about iPhone development. Tell some other better sites for easy learning about SDK codings if you know...

Thank you all...

Start at a hello world and work your way up. The best way is to just purchase a book on the subject.

This one looks pretty basic http://www.amazon.co.uk/Beginning-iPhone-Development-Exploring-SDK/dp/1430224592/ref=sr_1_1?ie=UTF8&s=books&qid=1281003097&sr=8-1

Apple documentation is wonderful. Begin with Learning Objective-C: A Primer to familiarize with the language and then take a look at Your First iOS Application.
