I think the RAWs are mostly untouched, but SLR jpegs are touched too.
The first picture is untouched iPhone. The second is an iPhone 4s (HDR on, and a big difference it made) photo touched with Snapseed. I just find the ease of using mobile so much better... I can still get better pictures with SLR after I set it up, change lens, zoom... etc etc. But still can't get a good wrist shot like iPhone...
