I just pre-ordered the iphone 7+. And part of the process asked me if I wanted to trade in my current iphone 6. I said sure. During my last upgrade/pre-order to the iphone 6, I got like $125-$150 from verizon for my phone. So, it gives me a little appraisal questionare and everything is perfect with my phone, so I selected the corresponding boxes. Then I clicked appraise and they are offering $36.90 for the phone. I contacted Verizon and they told me that this is the outright trade in value. $36??? So, I declined the trade in and will be keeping the phone..for now. I checked out Gazelle, and they are offering $190. Are they going to be the highest? Or are there other sites? I went to Amazon but it looks like they only accept unlocked phones. Mine wouldn't be considered an unlocked phone, right? Or would it? Looks like Verizon is offering $295 for my phone. What exactly is unlocked? I thought it meant a phone that doesn't belong to a carrier. Thanks!
