Hey guys, So I am looking to have my iPhone 4 replaced for several reasons. One of them being that my camera lens has been scratched up and it is nearly impossible to take pictures through it and also I find iOS 7 unbearable to use on the iPhone 4. I heard that when Apple replaces an iPhone in their store for half price (which I think is $150) they actually are giving you a refurbished iPhone. Since I had this phone replaced over the summer due to water damage, they are giving me a hard time about replacing it again. I was wondering if it is possible to simply buy a refurbished phone from them for the discounted price of $150 rather then going through the replacepent process. If so, is it possible for them to give me a phone running iOS 6 or iOS 5? Thanks!
