Four things iOS 7 tells us about Apple's next iPhone

Apple has played the game long enough to keep its secrets heavily guarded, but a close look at some of iOS 7's lesser-known features hints at a few hardware changes we should count on (or not) for the next iPhone -- and maybe for the next iPads, too.

It doesn't take an OS upgrade to guess that Apple will improve its camera's still-life and video capture hardware. That's a given.

Now here's a little evidence: iOS 7 supports 60fps video capture, while 30fsp is the smartphone standard. That means that the next iPhone could capture twice the information in the same span of time; I'm thinking at a resolution of 1080p HD.
