i dont think there's been much testing of the two cameras? just did a quick google search and yeah there doesn't seem to be any direct comparisons yet
however dpreview has a photo taken with a 4S (that was taken on a different day/time) in nearly the identical spot that apple took a photo for one of their sample images
iPhone 5 vs. iPhone 4S: Image comparison: Digital Photography Review
looks the same pretty much but cant really compare accurately
but anyway why would you guys care about the camera in either of these phones they're crappy cams
*insert nokia gloating*
