how are you guys getting replacements over the phone? I have scuffs, but I also have a legitimate problem with my ringer. tech support tried walking me through things for the defective ringer/vibrate, but no luck. she said to go in the store and have a genius check it out or send it in for repairs (wtf). and another rep I talked to about the scuffs said to try the store. problem is, my store doesn't, and hasn't had any in stock. they have the white box replacements, but I don't want to have mismatched serial numbers on a phone 4 days old. I feel like I'm getting a runaround from Apple.
