My sister wants to sell her VZW iPhone 4 (which has unlimited data) and replace it with an iPhone 5. She is completing a sale on eBay (buyer paid, just need to ship) however, she just now realized that she won't have a phone. And I also wondered about her phone number, which she didn't want to lose along with the unlimited data, if possible. Anyway, is there any recourse? or will a transaction cancellation be needed?
