Is there any reason to get the Nike + sensor if I have an iPhone?

I recently purchased a pair of Nike running shoes that have a spot for the Nike + sensor and I've always just used the Nike running app on my iPhone when I run so is there anything the sensor could do that the app couldn't? I figured probably better tracking of elevation (I run in a really hilly area), but other than that I wasn't sure if it was worth looking into.

Why does my iPod on my iPhone crash?

Okay so I open my camera (no, it is NOT on video setting, I know the music fades when the video is on) and it just crashes. I have an iPhone 4S, and lately it's been laggy and crashing. Can anyone please help me? It's driving me crazy! Also, it just sometimes crashes all of the sudden. I have turned off the Facebook from your phone thing, because I read that it makes your phone messed up. Please please help.

Will there be an iphone 6 and 7 (etc)?

Will they just keep going until the iPhone 384 or whatever? And will they be the same size as the iphone 5 or 4? Because what if someone wants to buy a case but then the new iphone comes out and they buy that one and it's in a different size? That case will never be used again… Sigh i wish they'd keep the size and shape the same. But will there be more iPhones?

Added (1). Yes what annoys me is they keep making it taller… I don't think it looks good:/ And all those skins and cases from your old iphones go to waste… Ugh.
