Is It Safe To Say There Will Be No iPhone 5?
In past iPhone releases, there have been leaks of internals and even as the iPhone became more popular, leaks of the entire prototype device.
Seeing as there have been zero leaks in regards to any hardware of the iPhone 5, and there have been no references of a future iPhone in iOS (aside from the iPhone "4S"), I think it's safe to say that all we will be getting is an iPhone 4S:
A5 (definite)
More Ram (probable, if it's an "S" model)
World Phone (GSM & CDMA in one package) [Not confirmed, but rumored a lot]
Beefed Graphics (probable, if it's an "S" model)
Better Battery? (probable, as leaked hardware hints at a slightly larger and modified battery)
8MP Camera with potential improved flash (Not confirmed, but rumored a lot)
Either that, or Apple miraculously was able to keep leaks from occurring for the first time ever in iPhone history (likely impossible, even for Apple). Or, the iPhone 5 will ship weeks/month from now as it hasn't begun production, thus no hardware is out in the wild. However, I find that this would be detrimental to their sales model if they announce a product weeks/months before sales, as they would be competing against their own phones. That said, they would hold off on the iPhone 5, which if not announced alongside the iPhone 4S, would be released in 2012.
