[soopacee]

when i called t-mobile the other day for my crappy phone and the million issues i have with it......one of the things they asked me was to take battery out, and look for a small circle sticker......and they wanted to know what color is was


mine was white


what the hell does this symbolize?....anyone know??

That is a water damage indicator. I think white is OK. If you dunked your phone I believe it turns red.
