Remember how every time you have to enter your password, whenever you download an app from the app store.
That’s all about to change with the new iOS 6. The third-beta of the iOS 6 has been released and users no longer have to enter passwords for the new free apps being downloaded, or the apps that they have downloaded in the past.
Small nuisance like this only get tweaked with time.
As far as the security goes, considering the fact that you are downloading a free app, or an app you have paid for already in the past. It wouldn’t hurt, even if your little kid accidentally downloads some thing, you won’t be charged because you have already paid for the app.
Nice, folks at Apple finally realized this!
