How to maintain 2 different versions of an app on the iphone

Question

Is there any way to maintain 2 different versions of the same app on the iPhone? One version is the actual production build and another version is the development build which I can use for experiments ie UI changes

Answer 1

Xcode 4 allows you to create targets for your applications. You might find those useful. I use them to maintain a free version and a paid version of my apps.

Each target should then have a different bundle ID as this is what the phone uses to distinguish different apps. If you need a specific ID, (ie for push notifications, game center or iads), I'm not sure on a solution sorry

Answer 2

You can change the Bundle ID of the development version. You can install different versions of the same app if the bundle IDs are different.
