I am trying to upload my binary files for submission to Apple and despite looking through the documentation I can't find out exactly what I need to zip and where it is.
Go to developer.apple.com/iphone, log in, then click on iPhone Provisioning Portal. On the menu on the left, click on Distribution. There are several links for building for distribution, verifying a build, etc. Every step is illustrated and documented in detail, including what to zip and where it is.
