Alright, so both the rep on the phone AND the rep in the store have said it's a brand new device. The way it was explained to me was as such: When the phone comes off the assembly line, verizon takes a batch off the line and designates them as "replacement phones", so they aren't going to the store, they are being held for situations like this. They arrive as they do because they only send what's defective. By this logic if there isn't a battery issue they just send you a phone and nothing else, if there is a phone and charger issue, they'll send you that.
I'd say this makes sense to me, and this phone feels brand new, and like I said there was no refurb date in the ##778 screen so I think it's good. This morning while streaming radio (NPR) I received a phone call and there was an AWFUL screeching noise coming through the earpiece, which happened with the next call I placed too. I restarted the phone and all was good; I've also since done *228-2 to update just in case. The issue hasn't repeated but I'll obviously let you know if it happens again. I hope this was a one time interference issue (maybe with speakerphone, for NPR, and the earpiece, for the call).
The best of luck to you TBolt, if you're nervous do the ##778 -> view -> display and see if there's a refurb date, hopefully there isn't one
