Hi everyone. I purchased an iPhone 6 last week from the corporate Verizon Store. I was hoping to get a 6+ but they were sold out. I am on the edge program with 3 other lines. If I were to purchase a 6+ from either Apple or Best Buy as an added line on my account, also using Edge, could I then return my regular 6 back to Verizon and have the 6+ transferred over to that line so I could keep my same number and account?
