I'm sure it works as quickly and smoothly as it did in 2009 too.Really, I bet it would if you could downgrade to iOS 3.
What does that have to do with it iOS devices having a two year max lifespan, since that was comment was directed to (and quoted for good measure).
Oh right, I'm supposed to pick up on the dry wit and eyebrow waggling that you did while you were typing that expresses the obvious sarcasm that was astonishingly similar to half the other complaining posts.
And no, it doesn't work as quickly or smoothly, it also has applications on it that didn't exist in any form, as it has gained functionality it has lost responsiveness, but not to the point where it's useful lifespan is at an end. But hey, why actually talk about something when we can just snark back and forth.
