iPhone app version and build numbers

Inner Exception: iPhone app version and build numbers

The steps:

1. In your Target Build properties set Versioning System to apple-generic
2. Set Current Project Version to something (e.g., 1).
3. In the project dir run: /Developer/usr/bin/agvtool next-version -all (this or similar needs to be run to inc the build number each time (e.g., part of your code commit))

4. Access the build number as a string like: [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"]

Tip: If you right-click on any of the properties in the Info.plist view, click Show Raw Keys/Values.
