Can you get camera RAW from an iPod/iPhone 5?

I have a lot of high end camera equipment, but find that the iPod 5 is so handy that I am starting to take a lot more photos on that rather than my Nikons.

I know I am sacrificing a lot for convenience but would still like to get the best images possible.

1. Is there a method of getting camera RAW from an iPhone?

2. What is the optimal format from the iPhone?

3. If I chose uncompressed jpeg as the Export format from iPhoto/Aperture, is that already too late?

4. If so where and how do I get better versions?

5. Can anyone refer me to a workflow that will extract the best possible image and then clean it up?

Thanks

Peter
