iphone app sample code

I'm wondering if theres any good sites for sample code for iphone apps. I'm trying to make a very simple app for a small website. I'm not familiar with Objective-C but have had some experience(the basics) with Java. All i really want to do at first is have the app navigate to the mobile website. Later on i'd like to add things such as navigation buttons and google maps but i just need a good starting point without getting overwhelmed. I'm hoping that through some guess and check and messing around with code i might be able to make a really simple app to put out there, since i'm not familiar with objective-c.

Also if anyone knows any good books/tutorials to follow to get started that would be alot of help as well.
