Touch Pro Replacement

[Baffles]

So I got my replacement Touch Pro from UPS late last week, but between finals and a family event over the weekend, didn't have time to open it up and look at it until I got home from my last final earlier today.

All was nice, sturdy build quality, earpiece had mesh across the whole thing instead of just on the side, etc....


... Then I turned it on.

Almost looks like water damage to me, though I'm not totally sure how it would have gotten like that in shipment. None of the water sensors are tripped though, so I dunno. Hopefully Sprint doesn't try to blame it on me, I don't know if I should call them up and get them to send a new one, or if I should drive 40 miles back to my corp store and show them.

Anyone seen anything like this before? Any suggestions as to if I should call/visit corp store vs calling Sprint directly?
