Got a "new" replacement TP2 from Sprint, but it seems used?

[Procter]

I just got a "new" replacement Tp2 from Sprint. It arrived in the retail package, however it didn't seem right from my previous experience of new phones.

1. Battery is unwrapped
2. There are tons of dust particles on the screen protector which seems like it has been removed before and got very dusty.
3. Once powered up, it did not ask me to do the touch screen alignment etc, but directly boot into WM OS.
4. There is a strange number 000-000-677 associated with the voicemail when I clicked on the dialer.
5. ##778# shows that it's produced in 02/10, and never gone through refurb process. The life time counter is 0 with timer of 0, so no one has used it to do a voice call before. But there has been data usage already (2mb in received and 2mb in transmitted).

Sprint CS argued that the 667 is a special number HTC used to program the phone and it does use small amount of data. But I do not recall my first Tp2 showing anything like that.

Is this a used phone judging from my observation? TIA.
