When I check my account online, I see the above picture for the 4 phones in my family plan. Would I be able to do the buy-back program through Sprint (or other companies) and purchase the iPhone 6 (or 6+) or do I have to wait for the 141 days? The website is confusing and it does not clearly explain this procedure. Also, if ONE of the 4 phones is upgraded, will the other 3 phones' "Your next discount will be available in ____" be reset? The 4 phones were NOT upgraded at the same time last time around the iPhone5 came out so I don't understand why all of them say 141 days left (2 of them were upgrade earlier but the 141 days seems to be when the latter 2 were upgraded). The representative last time told me that each of the phones would retain its own upgrade date based on when THAT particular phone was upgraded, but apparently he was wrong.
