Software update

iOS 6.1.4 is the current version but iOS 7 will be out this month.

Go to Settings > General > Software Update.iOS will automatically check for available updates. Available updates download automatically if your device is connected to Wi-Fi and a power source.

If you have iOS 4.01 you will not find any software updates under Settings. This feature was introduced in iOS 5.To update your phone you just need to connect it to iTunes. Then select your phone and an update process should be waiting.

  • Update stopped during ios update own iphone now phones broke I connected my iPhone 4 to my computer (iTunes) and started doing the update through iTunes. About five minutes into the update iTunes in my computer stops working, causing the update to of course stop working. Now my phone will not turn on. On the screen it is black with the 'charge symbol' as if it were low on battery and an iTunes symbol. I have tried turning my phone off and on, but of course it didn't respond.
  • New iOS 6 update, find my iPhone update? I don't like the new find my iPhone update is there a way to change back to the old find my iPhone but keep the new update? It's not showing locations like it used to and won't even how me major boroughs like Croydon. Streets are difficult to see, much smaller picture. General *** compared to the older version.
  • Is the IOS UPDATE 11.2.2 update The one that is supposed to slow down the older Apple Phones? If this is the one, I don't want that. I have an IPhone 6s+.
  • Is the iOS 6.1 update on iPhone 3 safe to update? On my first iPhone there were problems, and the update didn't help it wiped out everything and among other things had to get a new iPhone. The iPhone I have now works, so should I risk this update? It's a 3GS.
