Mobiforge published today an interesting article by Wei-Meng Lee on the key steps required to test and deploy your iPhone app.
If you have successfully published on iPhone before, there will be nothing new for you, but if you haven't, the article gives you a simple guide for deploying your app.
The article kicks off by saying that "a repeated criticism from iPhone app developers comes from the difficulty they find in deploying their application to a real iPhone or iPod Touch. Apple, for better or worse, has designed a process involving many hoops that must be jumped through, and this has prompted developers to grumble, and others to explore alternative, non-official open tool chains, which do not require app signing. In this article, I will walk you through the steps you need to take in order to test your iPhone apps on a real device, be it iPhone, or iPod Touch, the official Apple way."
