When I tried to submit a new version of an iPhone app to the App Store after making fixes, I encountered the following error:

The binary you uploaded was invalid. The key CFBundleVersion in the Info.plist file must contain a higher version than that of the previously uploaded version.

The Build version needs to be higher than the previously submitted version, and it was caught by that validation.
