4. Just Start Writing:

Give yourself a project and start working. If you can't face starting out on an original project, Varrall suggests a couple of modification tasks. "The SDK actually comes with a whole host of sample projects that cover most aspects of development. So the best place to start would be to take one of those and reverse engineer it and work out how it has been constructed. You can then build on these by adding new features and create your very own game very quickly."

5. Sign-up as an Official Developer:

If you plan to release your app, you'll have to sign up with the iPhone Developer Program. The standard cost is $99, and you will have to agree to Apple's terms and conditions, and sign and return the contract. It’s important you know that you'll need to sign up in order to test your code on an actual iPhone instead of an onscreen emulator. Once you're on the Developer Program you will receive a certificate, which allows you to pair up with an iPhone device.
