If you're like me, you may have had some trouble getting your Adobe Flash CS5 iPhone exported application working with the iTunesConnect Application Loader. This is probably because Adobe Flash CS5 exports an .IPA file, which you can upload to your phone for testing, and you need a .ZIP to upload through Application Loader. This is a quick tutorial on how to solve the issue.
This is assuming you've already tested the app, got the proper provisioning certificates and all that jazz.
Change the extension of the newly created .IPA file from .IPA to .ZIP. It will ask you if you want to change the extension of ".IPA to .ZIP". Say yes. For example, you would rename "yourapp.ipa" to "yourapp.zip". Refer to the picture.
Now double-click on the .ZIP file and it should uncompress itself into a "Payload" folder.
Inside the "Payload" folder is a .APP file/folder named the same as your original Flash file. Right-click on this file and select "Compress 'yourapp'" and it should create a new .ZIP file for you. Refer to the picture.
Use Application Loader to upload this new .ZIP file.
Good luck and see you on the appStore!
