iPhone 4S review @ Engadget
 

This isn't the iPhone 5. No matter how badly you wanted something slim, sleek and wedge-shaped, this isn't it. If you went ahead and got your hopes up ahead of Apple's "Let's Talk iPhone" event, hopefully you've gotten over the pangs of discontent by now, because this device pictured front and center is the iPhone 4S. It's a new spin on an old phone that will shock none, but give it half a chance, and it will still impress.

The iPhone 4S comes with a faster processor, a better camera, a smarter virtual assistant and twice the storage of its predecessor -- if you don't mind paying for it. Like the iPhone 3GS did before to the 3G, the 4S bumps the iPhone 4 down to second-class status, leaving those Apple fans who must have the best aspiring to own its decidedly familiar exterior. Apple says this is the most amazing iPhone ever. Is it? Yes, of course it is, but read on to see whether it's really worth an upgrade.
