Apple has begun rolling out iOS 6 to South Africa.
If it isn’t already available for you right now, it will be in the next few minutes
You can get the over-the-air download directly from you iOS 5 device by going to Settings > General > Software.
Alternatively you can connect your device to iTunes and hit the “Check for Update” button.
If you haven’t already, you will need to update to the latest version of iTunes for full compatibility with iOS 6. Grab it here.
