Okay, so long story short I had Verizon and an iPhone 4. We switched to AT&T so logically I had no use for a Verizon phone so I resold it. Evidently since we canceled Verizon mid contract, they put the phone on blacklist until November 16th when the accounts billing cycle is up. I had NO IDEA when I sold the phone that this could happen - I thought if you just canceled the service you're free to go as long as you pay the current bill & any money you owe the service provider. Anyway, the phone will definitely be able to be activated on the 16th but not before then. The guy I sold it to is now coming at me saying he's going to file a police report, take me to court, ruin my life etc. What do I do?
