I bought an iPhone 5s 64GB from a guy that says he got it as a replacement phone from Apple 2wks prior. I was assuming it would still be under some kind of warranty by apple for a year (now I found out 90 days). I entered the Serial Number at the Apple website to check on warranty status and it says warranty has expired. I guess I was lied to by this guy on his craigslist advertisement. He seems quite legit. My phone works great, except occasionally flickers. Sometimes the swipe up and swipe down stopped working unless I reboot (which I think is an OS issue). The battery life is poor too. I needed a new phone and rushed to buy, but hindsight should have waited to order the iPHone 6 plus instead. Lesson learned.. Don't trust people on Craigslist.
