I have a 3GS that I purchased for my granddaughter to use until her upgrade time next January. I read everywhere that the 3GS is compatible with the iOS 5 and soon to be released iOS 6 which is why I purchased that particular version ... but itunes keeps telling me that the software is up-to-date and it is 4.x.x so I'm not sure what I need to do to update the software on the 3GS. Any help would be greatly appreciated.
