My wife and I are ready for upgrades for our launch day iPhone 4S models. Mine is a 32 gig model (work paid!), hers is an Apple store (just replaced with new last month) 16 gig model. When the 5S comes out, we'll upgrade. Thinking about our two tween boys. Pretty responsible for their age. Initially, I thought we'd pass our iPhones down to them after getting Otterbox Defender cases for them. Now I am wondering whether we should trade in the 4S phones (when we get the 5S) and then get 5C iPhones (Otterbox?) for the boys. I feel a little crazy for even thinking about getting iPhones for kids, but we'll have these phones just sitting here otherwise and middle school is when kids get phones in our neighborhood. I know we'd be under contract with the 5C phones. And although the boys are responsible overall, I work with teens, so I have seen more than my fair share of cracked screens on iPhones. Makes me worry about a 2year contract. At the same time, my wife's phone was just replaced for speaker issues last month, so I know the phones do not last forever. Also, my 4S is a 32 gig model vs what I expect would be 16 gig models for the 5C. You can see, I go back and forth. Any opinions on what would be the best plan of action for the iPhones for my tween boys?
