Ok, so I was unfaithful. I sold my 6 Plus and got a Note 5. While I actually love the phone and use Google services, I just cannot live with the battery life. The 6 Plus has me spoiled. Tomorrow is my last day to return the device and I don't have a device. Also the 6 Plus S is coming and if I am going back, I might as well get the new phone. What is the best way to return this to Best Buy, grab a prepaid or burner, and pre-order the 6 Plus S? The return part is easy. The Pre-Order is easy. The question is more around the phone I have to live with for a few weeks. What do you guys suggest and what would be the best deal?
