Iphone Threat

Hi, i have a otterbox defender (http://www.otterbox.com/iPhone-4-De...XX_color=20&start=1&cgid=apple-iphone-4-cases) for a case for my iphone 4s. it covers the headphone jack and the connector. I recently took out the screen protector that came glued onto the otterbox case and put a ishieldz screen protector and im wondering if snow could damage my iphone even though the headphone jack, connector is covered. The sensors are still white so i know it's not water damaged but i turned it off when i found my phone in not even an inch of snow with the screen down and little snowflakes on the speaker. Once i cleaned it off i put it in a bag of rice and im wondering if the snow could damage the screen and the internals through the screen and speakers, it was only in the snow for max of 5 minutes.

 

Thank you for your input
i would still like to know what other people think of my situation
