After receiving it, I took it to AT&T. The rep swapped sim cards and the iTunes activation still showed the seller's number. Then called Apple and have a case that is escalated. I'm waiting for a call back from them so they can delete the old number. It's been 4 days. 
Anyone else have this problem? The Apple guy and AT&T rep said this never happened before. I feel like maybe the lady mixed up the sim cards or something. Doesn't make sense as to why I'd be the only one with this issue.
