So, long story short, I sell my iPhone every year and get the new one. I have done this for about five years with no problem. Anyways, I was setting up my new iPhone 7 Plus yesterday and was having issues so I decided to restore to factory settings and start over. When I plugged it in to iTunes it said that the phone was tied with my Apple ID and I needed the password to do stuff to the phone. This obviously wasn't an issue because it's my phone, but is this going to happen now to the person I sell my 6s Plus to? I factory cleared it and it is on the "Hello" set up screen. Will they be able to use it without my password? In hindsight I should have logged out of my apple id before clearing it.... Anyways I have to ship it out within the hour most likely so any help with this would be awesome. Thanks!
