I just got a replacement from Apple due to something weird happening with my screen recently. I've been thinking about rocking it without a case since were semi-close to the iPhone being refreshed again. Which made me wonder: how long have you guys been using your iPhones without a case? Any problems/blemishes/scratches? Have you dropped it? I'm talking about 100% case free which also means no screen protectors. Hows it held up?
