i finally put my first gen iphone to rest and got a 16G black, but had to exchange it while i was on a trip. it was within 14 days of original purchase, but i didn't have the original packaging with me. so the genius gave me a new phone, and it was in a slim white box with nothing on it. 1. does that mean it's a refurbished one? 2. can exchange it to a new one since i'm still within 14 days?
