IPhone :: 4S Photo Import Image Corruption Creates "color Lines"

Ever since I got the Iphone 4S, it's been corrupting my pictures occasionally during import. It's sad, because I usually have it set to delete the image after importing, so the uncorrupted image is lost forever. Below is an example of how the import destroyed a really nice picture of our newborn baby.

I'm running snow leopard, with iphone version 5.1. Originally I was using iphoto to do the import, but I read somewhere that image capture might fix this problem. But the problem still occurs even with image capture. Sometimes there are multiple "color lines" through the picture, although the one below only has one. Also, sometimes the image doesn't just change color across the line. It can also become misaligned, so tweaking the color isn't enough.

I'm not sure about this, but I think the problem may occur more frequently when I have a lot of apps sharing CPU. So I suspect it's a bug related to context switching. I'm not sure whether snow leopard or the iphone is the problem, although I don't remember it occuring with my older iphone 4.

I have noticed the problem tends to occur in batches of consecutive photos, which is why I think it has to do with memory swapping due to concurrent applications.
