After iOS 6 beta 3 launched, some noticed that the beta OS was not requiring users to input their App Store password when downloading free applications. It appears that Apple has reversed this in beta 3 – over the air – or the situation is not spread across all users.
@markgurman Refer to my tweet yesterday. The behavior has changed several times, people need to stop talking about it.
