i never had an iPhone 4. went from 3GS (no flash) to 4S (flash) and photos are no good when i use the flash. there's a weird "rainbow" effect on the photos when the flash is used.
i can't imagine i'm the only one, but there don't seem to be any complaints about it...
anyone else? is this a common issue?
(fyi - bare phone, no case, no "plastic" backing. my finger's not in the way, threre are no mirrors or shiny surfaces in the area...)
