Engadget - It's not an iPhone mini or anything, but it's the first iPhone with Siri. And that has to count for something, right? Right? While it's no iPhone 5 (not even close, really), the iPhone 4S is far from being "last year's iPhone," and the greatly enhanced camera, bolstered A5 dual-core processor and inbuilt voice command should provide plenty of reason for folks to upgrade if they're near the end of their contract. Furthermore, having the option on Sprint -- despite Apple almost announcing it as an afterthought -- is bound to make folks already entrenched on the Now Network think twice about what their next phone will come upgrade time.
