As far as I can tell (and I'm still learning too, so I could be very wrong), it's just basic Objective-C and Cocoa development, using special controls and objects in the iPhone SDK.
I found a pretty good tutorial if you need to get Objective-C down and you're already familiar with C:
http://cocoadevcentral.com/d/learn_objectivec/. The rest of the site should have some other good resources as well, but I haven't looked around much.
That should get you going. From there, browsing through the examples and such on the iPhone dev site should provide enough guidance on specific iPhone controls and such.
I should clarify. I don't need help with Obj-C, or API references or that sort of thing. The SDK documentation is pretty good. I need help with specific problems I'm having with the API.

Try some of the mac sites.
Like macrumors, etc.
I frequently read MR, so I guess I'll go there.
