...but I have no idea where to begin. Any advice would be appreciated. I'm presently an Art Director/Graphic/Web Designer. Outside of HTML and a little bit of Flash Actionscript I'm code noob.
You need to know Objective-C. That's Apple's preferred programming language for, well, everything on iPhone OS going forward. They're also mandating that developers use approved programming environments, so this is a good time to get familiar with Xcode. Once you know Objective-C and are comfortable working within Xcode, you can get an iPhone SDK and poke around. There are quite a few APIs to get familiar with, like Cocoa Touch. Apple's developer center is a good place to start, but in general, it assumes you already know what you're doing from a programming standpoint. There are a couple start-from-scratch articles, but I can't vouch for their quality. I'm getting royalties for this, right?
desides, are you in the cellular industry or something? you seem to know an awful lot of specifics and you are supposedly only 25. you were quite helpful in my thread about getting a phone.thanks for that btw.
Fin D, some news for you. There's a rumor that on Monday at WWDC, Apple will release a new version of Xcode. If you're still serious about iPhone apps, you'll want to keep a close eye on the Stevenote.
