We just released 1.0.0 of Aliens versus Humans and plan to release an update prior to Dec 22. I'm guessing that as long as the bundle ID doesn't change, Apple likely doesn't care about versions as long as the version changes. My concern is to preserve the saved games that users will have from 1.0. Essentially what I'm doing to test is to have 1.0.0 on my phone then I produce an ad hoc distribution of 1.0.1 and download it. Then I load saved games that continue to exist from 1.0.0.
I think that is as close to testing what will happen in the AppStore as I can get.
Comments/suggestions?
