I want to understand the difference between updating iOS through OTA VS through ITunes.
I see that the update size on ITunes for iOS 8.3 is more than 1 GB as oppose to about 280 MB through OTA. Is there any difference between the end result of downloading through Itunes ? I understand that ITunes downloads the whole build, but does it make any difference? Please share wich way would be a better option to go with for updating iOS.
