Really? You get this from where? From what I recall, there's only been a single iPhone named after a number (iPhone 4) and a single iPhone with an S (iPhone 3GS).
There was never an iPhone 1, 1S, 2, 2S or even an iPhone 3 (that's right, the 3G was the second iPhone).
Oh wait, the 3G was the second iPhone?! Wow, with your talents and insight, you should be working at the Pentagon! Get offline and get a job there, now!
I guess some of us were able to see the pattern forming a while ago, and the rest of you who thought it would be a 5 are just butthurt that you were wrong.
"Nobody had that kind of foresight!" Yeah, keep telling yourself that while myself and the thousands of others who called this the 4S for the past year will just nod our heads and roll our eyes.
