Hi, when using my iPhone4s to take stills or movies I occasionally get pink and green striping across the image. With the attached movie there were also solid blocks of pink obscuring the image. Has anyone else experienced this, or know how to sort it out? I've had the phone since release and it started doing this about 2 months ago. http://www.xorro.co.uk/temp/IMG_0350.JPG http://www.xorro.co.uk/temp/IMG_0342.MOV Many thanks P.S. Yes, I know they are upside-down!
