I hate to bump an older thread ...
I know a poster already commented to stop replying to an old thread, but the only thing I haven't seen in here is a solution. I've had this issue with the phone for a while - funny thing is, I swear my iPhone didn't have this when I first got it (even looking at photos from when I first got it it wasn't nearly as obvious to me as it is now)... but I really am more curious about a solution in photoshop.
Does anyone have a png overlay they could share that will even the colors out? I've got some video from an event that just looks odd from the color distortion with a gradient.
