In a most peculiar timing, as most of Mojang is on airplanes flying to Vegas for MineCon, we've found that Minecraft: PE has been released for iOS. Whether or not this was intentional time will only tell, but for now, go and swipe it up for a cool $9.99.
UPDATE: It appears that the app is not available until the 17th. So if it's not available for you, you may have to wait until then!
That ripoff MC game in the that has been in the app store for about a year costs about half as much as the official one will. But you have to understand that you are paying for the official version and knowing mojang, they will probably update it periodically and improve the gameplay. Besides, $7 is not that much, considering the price of skyrim and mw3, which are,( to me at least) as great in caliber as minecraft
