My son has spend ages building his Minecraft world pocket edition on my iPad. However the iPad was stolen.
Is there any other way he can access his world from another iPad or laptop, etc..?
Restore on new iPad
If you are going to buy a new iPad, and backed up the stolen one you can easily restore the old backup and you will have the world back again. but you have to install all the apps (including minecraft again)
I recommend this anyways because it will be identical to you old iPad.
Save the old backup to a external storage, because it might happen that itunes overwrites the backup and everything is lost.
Restore on PC
