When installing the update on the iPhone 5 users will find that they have to install what is called an updater for the iPhone 5 beforehand. This download is 69.7MB and it should work fine, it did for us.
iOS 6.0.1 update rolls out: what’s changed?
After this the app will find new software and then ask if you wish to install the iOS 6.0.1 update. Bear in mind that your battery should be full at this point. So what changes can you expect from the update after installing it?
Is seems that a bug has been fixed when it comes to the iPhone 5 preventing software updates OTA. The horizontal lines seen on the keyboard should no longer be an issue too and the problem should also be fixed in relation to the camera flash not working.
The update will also make the iPhone 5 and iPod Touch 5g more reliable when it comes to WiFi connections. It should also stop your iPhone 5 connecting to cellular connections when it supposed to be using Wi-Fi. The “use cellular data” switch on iTunes Match should fix issues, along with the Passcode log bug, which allows access to the Passbook from the lock screen. Finally a bug has been corrected which relates to Exchange meetings.
