I bought the 4s, so sometime around october or november my AC+ will be expiring. A few chips in the edge of the screen (from falling out of my messenger bag while riding full speed across a busy street with no case and rolling about 15 feet on edge) but otherwise it still works fine. I don't know if i'll be upgrading any time soon (if anything it would be to get off sprint's horrible network in chicago), but I want to get my money's worth for the AC. How can I do this? I'm pretty sure I can get a new battery, but what else? For example, should i smash it so I can get a brand new one? Mostly kidding. I'm not looking to scam, just get it as polished as possible before the insurance expires.
