I really don't recall, but I'm guessing it was a major update. I believe this because I think I remember it being for the newer phones (iphones 4/5?) and that the update didn't include certain features on the 3g (this was a while ago for me, so I don't recall many details, sorry) But at the same time, there was no "Warning: This will actually slow down your phone and make the user experience suck." I'm okay if a phone can't support certain features that the latest model includes. But the fact that an update actually made my older phone worse off, was quite the disappointment.
