it's been happening to me a bit recently, eventually the vertical stripes go away but for now they've been coming on. if i take a photo that looks like it has vertical stripes, it doesnt come out when the photograph is taken. Anybody else? is this just a flaw with 4.0, 4.0.1 or 4.0.2 or is something hardware related? Either way, using my phone unlocked in Austria so it will have to wait before I replace it if it's hardware. Just curious though, don't remember this happening before.
