I currently have a 16gig iPhone 5, and I'm planning on getting the iPhone 5S. My question is: what's the best way to get my money's worth for my 5? I have AppleCare+ that I have never made a claim for, so right now I'm wondering if it's not the best investment to *eek* break my 5, take it into the store, get a flawless phone in return, for the $50 fee, and either trade that in for credit towards the 5S, or sell it on Craigslist or ebay. My 5 is in good condition, but has the normal scuffs, etc. for a phone that is a year old. Thoughts?
