Upload app to app store Process

Important notice from Apple regarding changes to binary submissions:

Beginning July 22, you will need to use Application Loader to submit your binary to iTunes Connect. Binary uploads will no longer be accepted through the iTunes Connect interface on that date.

Application Loader offers fast uploading, a more stable connection, and early validation warnings. You can now also submit binaries that contain In App Purchase using Application Loader. Make sure the status of your app in iTunes Connect is Waiting for Upload before you submit your binary through Application Loader.

If you have installed iPhone SDK 3.2 or later, you can access Application Loader from the Utilities folder (/Developer/Applications/Utilities/Application Loader.app). You can also download Application Loader from iTunes Connect.

If you have any questions regarding Application Loader, please review our Frequently Asked Questions or utilize the Contact Us system on iTunes Connect.

DUE TO APPLE POLICY YOU MUST USE AN INTEL BASED MAC(Power PC's will not work) TO SUBMIT YOUR APP FOR APPROVAL. IF YOU DO NOT HAVE A MAC, PLEASE CLICK HERE!

Your app status MUST say "Waiting to Upload" and not "Ready to Upload".  If you app status says "Ready to Upload", please click on View Details, then Ready to Upload Binary.  In order to be ready to deliver your binary through Application Loader, you will need to answer questions about Export Compliance.  Your answer is no.  Your app status will then say Waiting to Upload, and you can proceed with Application Loader.
