I have had my iphone 4 for nearly 2 years now, and ive never updated it but when i tried i always says failed to update? any help with this would be great
More information needed if you want help
Ive plugged it into the computer and connected to iTunes but it always fails. And also when i try to update without connecting to iTunes, when i go into settings there is no 'button' saying software update?
Update without a computer are only possible with iOS 5
