The other day, I was with my mom, getting a new 32gb black AT&T iPhone 5. I already had a white 32gb (since launch day), and decided I wanted to switch to black. Since my mom wanted a white 32gb, I told her that if she bought a black 32gb, we could switch. She agreed... So anyway, we were at bestbuy and the clerk could not get the iPhone to activate. After about an hour and a half, she finally checked in settings and the serial number, IMEI, ICCID (sim card number) were all mismatched to the box. I immediately said I want a new phone. The clerk was very understanding and grabbed a new one out of inventory. She was immediately able to get it to activate with no problems. So I'm just wondering... Has this happened to anyone before? I've never heard of iPhones having serial numbers mismatched to the box. The box was sealed and there was no sign of tampering with the phone. It had the plastic covers on it and all.
