All exchanges now have to be done in-store!
However, this doesn't change the rules, they're the same as they were when the thread started.
If you have a Priority 4 exchange (which is any TP exchange), you get your pick of the lesser phones mentioned ad nauseaum, and a REFURB TP2. At this point in time, the refurbs are mostly OOS because it's a brand new phone that's pretty well built.
If you've had THREE OR MORE exchanges in the past SIX MONTHS, you then become a Priority 5 exchange, which entitles you to a NIB TP2. This is Sprint policy! If the store is screwing you around on not giving you a NIB TP2 after your three exchanges, you need to tell them you talked to someone in Tech support who told you that there was something called a WEL List, and that you are what they called Priority 5, and you can get a NIB TP2, BUT ONLY AT A STORE.
Stores try to deny you a NIB TP2 even if Sprint policy would give you one for a few reasons: they're hoping for a sale, they don't want to lower their stock any (if they have one in the store, then they give it to you there), or they're just being *******s (love the stars).
Just remember, SPRINT POLICY says after 3 exchanges on the TP in six months, you can get a TP2. This is not something you should hesitate to pursue. In the long run, you're actually saving Sprint some money, because keeping the TP's in circulation is expensive for them. So you're being a good samaritan by getting your TP2.
