iOS Facing problem in iPhone and iPad build publishing

I had a iPhone project. Now it is completed and published on App Store.

Because it is iPhone App it is running on iPhone, iPod Touch and iPad with iPhone look.

Now I need to make this project for iPad with iPad specific screens (for say using split view). For that I changed it from iPhone to Universal.

I have created split view and few XIBs for iPad which is running fine but my application is in intermediate position for iPad.

Problem: Now I want to update App Store build (which is iPhone specific), but the current build in which I am working right now is Universal in which iPad changes are not completed.

If I create a build and publish in app store and when user download the build in iPad (because it is Universal) my uncompleted screen will be shown.

How to handle this situation.

If things are not clear I can give more details for the same.

Summary: I have a universal build with uncompleted functionality of iPad but I want to update this build on App Store because I made some changes on that.

This issue could be better handled if you are using 'software configuration management' (git, subversion, etc.) Are you?

Yes I am using, now created a branch of the app.

Thanks !!
