Hey guys. I have a weird situation that I want to run by you. I'll try to keep this short and sweet, but want to make sure to include all relevant details. My wife had an iPhone 6S that we purchased brand new at Best Buy back in October. We decided to switch carriers, and elected to sell the phone on eBay and get a new one with the new carrier. On December 12th, I took "Find my iPhone" off her phone, and did a "Reset all Content & Settings". On the 13th, I listed the phone on eBay... it sold and I shipped it the next day. When the buyer received it, he contacted me saying that it was iCloud locked. Impossible I thought. I wiped the phone myself. Sure enough, it was (according to iCloud.com/activationlock). So I contacted Apple support and went through all the hoops. The rep believed me about what was going on, but couldn't really discuss much in detail with me because I couldn't verify the account the phone was tied to (because it wasn't ours). All she could tell me was the email address was something like email@example.com (we don't have any Yahoo email accounts).... and that it was last modified on the 12th. And she also mentioned something about it being tied to China in some fashion (I'm not sure how). So this happened the same day I took her iCloud account off the phone and wiped it. But the phone had never been out of my possession. It was in its box on my desk. I sent in the requested proof of purchase to Apple and was told that engineering should have it unlocked for me within 24-48 hours. I was later told that it could take up to 14 days because of the holidays... so it's still locked right now. I'm sure they will unlock it for me, but does anyone have any idea how this could happen? I'm at a loss.
