I'm with barx on this one. I actually prefer testing my code and not just typing away, hitting compile, and thinking my code is perfect. There are enough untested apps full of bugs out there as it is. This would need to be something that maybe only happens on a Release Compile...and even then still an option since sometimes I compile code and slap it on my phone to test later and don't want to wait on the debug connection.
Right now we have an integer and a string to work with. I'd need a major version only I change and a build number that would be auto incrementing for this to be useful.
