Answer 1

I have accepted chown's answer as the correct one since it is very detailed and led me to the eventual solution, but I wanted to add this bullet-list answer for any future viewers who might want to see things cheat-sheet style.

Building the binary

• Edit schemes.
• Set archive scheme to use RELEASE configuration.
• Make sure code-sign for RELEASE uses client's App-Store profile.
  • Get this the same way you did in Xcode 3.2, you need his profile, certificate and private key.
• Build ARCHIVE.
• SHARE archive.
  • DO NOT RE-SIGN!

Send binary to client

(Email or whatever.)

Client uses ApplicationLoader to upload.
