Yeah, riiiightDudes, I'm taking bets on the name of this new iPhone. There is no new radical design and real 4G is in it. Thus ...
iPhone 4, totally new hardware design
iPhone 4S, a board upgrade, no new case design
iPhone 4G, new connector that takes Thunderbolt, taller and real 4G
We are not going to see "iPhone 5" for at least two years since I'm sure that is in Johnny Ive land going all over the place right now.
The iPhone 5 IS a totally new hardware design (electronically and physically).
The iPhone 4S already has 4G (per AT&T), so it wouldn't make any sense to claim 4G support was something new.
Unless the iPhone suddenly had a PCIe bus, Thunderbolt would be impossible; it would be impractical for an iPhone anyway.
