How to upgrade to a Verizon iphone and sell it on ebay?

I've searched for this question but all the answers (I could find) were from 2011 or earlier, so I want to make sure nothing has changed.

I like my current phone, but I'm eligible for a free upgrade to a iphone 4 with Verizon. I'm going to be with Verizon for the next 2 years anyway so I'd like to get the iphone to sell on ebay. I'm pretty sure I will need to activate it and use it for a period of time… Anybody know how long? And does anybody have a link that explains how I clear the data/unlock it/whatever else I need to do before I sell it?

Thanks!

Added (1). Yoda - I don't want to keep the new phone. I like my phone that I'm using now, and plan to use it for the next 2 years. So I want to upgrade, but then sell the NEW iphone on ebay to make some money. Sorry I didn't say that better originally… Thanks!

What seems to be the question here? I don't understand it the way you stated it.

Why can't you take your current phone to Verizon outlet store in your city, they will upgrade the phone for you, activate it & even transfer the old contacts from your old phone to the new. They can even give you a discount on the new phone if you want to sell the old phone back to them or you can keep your old phone & do whatever you want on ebay with it!
Your old phone will be Unlocked by Verizon automatically when you upgrade to the new.

So what are you confused about?

  • What are the best things to buy and sell on ebay? So I'm trying to make a just a bit of money off ebay. I'm trying to buy things off ebay then once I've bought them I will put them back onto ebay and sell them, and hopefully make a profit. So what are the best things to buy and then sell which would make me a bit of profit. I've already had a look at iPhones but they also go for too high of a price.
  • Verizon upgrade date? Any way to upgrade early? So today I went to the Verizon store to get the new iPhone 6. It came to 399, and everything was cool. But then, they realized I couldn't upgrade phones until March of 2016, and that if I still wanted the phone, it would come too around 800 dollars. So I was like yeah no thanks, and I left, all bummed out. So I was wondering if there's any way I could get the iPhone but, not for that outrageous price?
  • T Mobile or Verizon. Should I pay T-Mobile 175.00 for an upgrade or 94.00 to Verizon for new phone? I want the iPhone 6s plus. I'm already with t mobile but there internet is a bit slow sometimes. Its the jump plan ill get. Ill pay 12.00 for 24 mo. And if i get a new phone they won't run my credit again. But with verizon they'll run my credit. Is pretty good. But i don't want anybody to really run my credit tho lower it. I'm not sure about verizon internet but the commercials looks pretty good. They bboth have unlimited internet. What should I do?
  • If i upgrade to an iphone 5 can i sell it and keepvmy current phone? I'd like to extend my contract and get an iPhone 5 and the discount price. If I sell the iPhone and keep my current phone, will I have any problems with Verizon?
