qqp question1: Can someone find the picture of the Verizon iPhone 7 trade in chart? It showed how much each 7 would cost monthly after an iPhone 5 or 6 trade in. question2: I have an iPhone 4s with iOS 5.1.1 (never have any updates). Can I update the iOS to another version instead of 8.x.x, such as iOS 6 or 7, or not?
