iPhone Development books for a beginner.

[ericksgotmac]

So I'm going to college for Computer Science and as I was walking to the bathroom I saw we had classes DEDICATED to Mac specific activities. Now I have one thing in mind. What do I need to learn to make worth while iPhone Apps? I don't mean Pong-ish like games and etc. but actually useful programs that people will be intrested in buying. Right now we still have a couple months left before the semester is over so I want to learn on my own before I get into any classes. From my understand I should ....learn Cocoa, Objective C, and Java?

Any help on what I should learn and what books I should get in order to be able to code some useful apps.

Thank you!

You might look through the guides at the top of the iPhone Programming forum (http://forums.macrumors.com/forumdisplay.php?f=135).

This doesn't help me with what books I should purchase. Many people have recommended Objective-C by Stephen Kochun but he just released a book titled Objective-C 2.0 and I can decide if I should go with the first book or the latter? Does the iPhone even use Objective-C 2.0 or is that only for Mac ?
