In iOS 6 Beta 3, when downloading a free users no longer have to enter their password when download free apps from the App Store. In iOS Beta 1, you didn’t have to enter your password when downloading updates so it seems that Apple have expanded this very useful feature.
You only will have to enter y0ur password when you download paid apps and buy in-app purchases.
I wonder what took Apple this long to implement this.
