In order to submit applications to the iTunes store, you must first pay to become a member of the Apple's iOS Developer Program. Membership is paid, and starts from $99 USD (or equivalent), recurring annually. Even if you intend to develop and distribute your apps for free, you will still need to be a paid member of the iOS Developer Program. It is worth noting up front that only Mac users can follow and implement the steps for the iOS recipes since the building and distribution of iOS apps is only available to those running the Mac OSX operating system.
To register for Apple's iOS program, first open up a web browser and navigate to http://developer.apple.com/programs/register, and click on the Get Started link. The following page that loads will then ask you if you want to create a new Apple ID or use an existing one. Unless you have registered for some of Apple's developer services before, you should choose the Create New Profile link.
