Just out of sheer curiosity has anyone tested ios7 on a ip4, not a S, just a plain vanilla ip4. I just sold my ip5 in anticipation of a 5s and have been using an old ip4 I had laying around. On ios6 is LAGS pretty badly, it's kind of weird to see an iOS device lagging as despites it's otherwise glaring weaknesses ios has always been butter smooth. No complaints here, it's a 3 year old phone that Apple still supports so kudos to them. I was curious though if iOS7 will bring benefits to older hardware, or will the opposite happen and it will lag it even worse?
