I have an iPhone application built as an .ipa file. I also have my device registered on my Apple Developer Connection account. I downloaded the .mobileprovision and dragged both it and the .ipa into iTunes. The app shows up fine in iTunes. When I try to sync, though, I get
The application “FUBAR” was not installed on the iPhone “My Phone” because the application signature is not valid.
What am I missing?
Sounds like it might not work because the two files don’t match. You could rebuild the application with the updated .mobileprovision file. Also make sure you don’t have two conflicting entries in your keychain. An older one might be confusing things.
