I took this this morning before sunrise of the foggy conditions.
iPhone 4 iOS 7 Zoomed to frame HDR on Monotone filter applied
It's quite noisy.
I've noticed that using the zoom does introduce noise in the photos. In this case, it isn't really a detraction - kinda lends character to the shot. In other cases, the noise is not so nice to have. I think I'll try using no zoom and then cropping to frame in the future.
That's because there is no true zoom... the lens doesn't move in any fashion... so you're just zooming the file. It would be no diff to just take the photo w/o zoom and then crop it later. Actually... PS has some really good algorithms for enlarging so you would prolly be better doing it in PS.

Nice! I wish I could predict what my photos will look like with the iPhone. Some are fantastic, some are noisy as heck. Good thing there is a delete button!

You'll always get more noise the closer you get with a digital zoom -- it's all software and zooming-in just re-processes the same data. Unfortunately, simply cropping an un-zoomed digital photo and enlarging it to the same size will probably also result in artifacts/noise; It's all the same data, just blowed-up real good and massaged a bit.
Which is why using a digital zoom is undesirable in many (most?) situations ...

Carrying my Fuji around all the time is not an option, unfortunately. Shooting with the iPhone is convenient, if not reliable/consistent, when you have only a few seconds to grab a quick shot.
