Hi guys, My last iPhone was the 3G (not even the s!) so it's been a while since I've had an iPhone. (Been an Android user since then) Well, I figured it was about time to go back. As a college student I would like to save money so I narrowed it down to either the 5S or the 6. I would ultimately like to buy a used iPhone 5s as it would most likely be much cheaper, but I am dreading buying a used phone from a stranger and truly knowing whether it's unlocked, paid off, not stolen, and battery is not horrible. Note: Regardless of the phone, I am buying it UNLOCKED. Buying a brand new iPhone 5s from Apple seems a little silly, when I can put in a little over a $100 more and get the 6, but is it really worth it? Honestly, the screen size to me does not matter all that much. I hope you can give me some opinions as I am struggling making a decision. It's not like I can't afford the 6, but I would rather save money if it's not going to end up making me regret the purchase for the next two years. Thanks for any advice that you can provide, Cheers.
