Hello everyone! I'm about to purchase a second-hand iPhone 4S (get it from a trusted seller on eBay, for instance). Now here is the message I am extremely unwilling to ever read off my new iPhone's display: "This iPhone is currently linked to an Apple ID (******@****.***). Sign in with the Apple ID that was used to set up this iPhone". Please tell me, exactly which actions shall I ask the seller to take before sending me the iPhone, so that I don't run into the Apple ID link issue once I update or factory reset it. Thanks in advance, folks!
