Minecraft is an online game and cannot be cracked. You update Minecraft on your iPod or iPhone by visiting the iTunes stores and clicking the update button.
The Minecraft launcher (when you first start the game) will ask you, when there is an update available, if you want to update or keep the old version.
Mojang tend to update the game every 10-12 months as of 2016.
If you have already purchased Minecraft PE, then update the game.
It is already out. If you want to update your game to it. Open you Minecraft Launcher, click options, and then click force update.
When a Minecraft update comes out, your game will automatically update to the newest version. However, you can change what version you are on by clicking edit profile on the launcher.
Simply launch the game and click "Yes" when it asks you to update.
When the full Minecraft game is released you will have it if you buy the beta.
Minecraft is no longer in the Alpha stage. It has been updated to Minecraft Beta. Update your Minecraft game client.
The regular download as of Minecraft 1.8 is the Beta Minecraft. The last Minecraft update I believe will be the "Final" product and official game and no longer be a game in Beta.
'Minecraft' has an update/modification that you can install and use, called 'Pixelmon' which allows the user to use Pokemon within the regular 'Minecraft' game.
