I'm not sure there is any such thing as a "simple spec bump" when it comes to iPhones.
Need proof? Look at the simple spec bump the 3Gs got over the 3G...
Try running iOS 4 on both devices. The 3G is useless and the 3Gs is ok. I think that's more than "simple" but that's just my two cents.
Agreed.
Can we drop the debate whether it'll be a 4S or a 5? iPhone 4S was labelled by some random developer who was just using a Dual Core A5 chip to test out their app. Now everyone has blown this out of proportion and think that the next iPhone will be "just a spec bump".
Somethings to keep in mind.. a spec update is huge. A Dual Core iPhone will blow away all previous iPhones out of the water. But it won't be "just a spec bump", it'll be more.
WSJ says that the next iPhone will be thinner and lighter, aka external hardware redesign.
Also apparently the iPhone 4 design "fell out of favour" by the Apple execs. I don't blame them, because it really is ergonomically horrible.
Also, the iPhone 3GS was named because it made no sense to go from iPhone 3G to iPhone 3 in a marketing sense. Consumers want to see more added to the product, not less.
I'm sure the iPhone 3GS was an anomaly.
iPhone = iPhone 1
iPhone 3G = iPhone 2
iPhone 3GS = iPhone 3
iPhone 4 = iPhone 4
iPhone 5 = iPhone 5
Also, last year we had the following specs and features..
A4 chip, iOS 4, 4th generation iPhone = iPhone 4
This year we have..
A5 chip, iOS 5, 5th generation iPhone = ?
I don't know what it'll be named, but iPhone 5 suffices until then. Anything else really makes no sense (aka 4S, 4G, 4GS).
Sadly, a lot of iPhone 4 owners who are filled with buyers remorse want the next iPhone to be "just a spec bump". Truth is, it won't be just that.
