Iphone application development?

Iphone Application Development

IPhone application good for business…

1) You need a Mac
2) Sign up as an Apple developer
3) Download XCode for iPhone and the sample programs.
4) Get a developer key for your iPhone and your account, so you can install software to your iPhone. The simulator doesn't work with the accelerometer or multi-touch display, so you need a real iPhone.
4) Play with the sample programs, learn Objective C and Cocoa development from a book or tutorials.
5) Pay your $100 to get access to the publishing section.
6) Sign tax documents, verify your address, sign a million disclaimers.
7) Publish your applications in the App Store.

I'm up to step 6 myself.
