Its a moisture indicator, it turns slight pink when exposed to moisture (Sweat, steam from shower) and bright red when submerged in water. When I use to work in the Retail world for another company, I would have to persuade my manager to do a early upgrade. I know now it is much more difficult for managers to overrideto it to allow a customer to upgrade early. Asurion is the biggest rip off, they send refurshished phones and half the time they end up going bad after the 90 warranty period ends.

I would ask to speak to a manager and see if and what they're willing to do. January/March is usually the best time to do it, because it is harder for retailers to meet their quotas and will go above and beyond to make a sale.
