take it apart put it in a bowl of rice and let it dry out for a few days. i sent my phone in after it had been in a hot tub for a good 15 minutes. The moisture detection stickers had changed and everything. The screen was all fogged over too. I took it in and said it didn't work anymore and they sent it in and i got a new one the next day. It's worth a try.

in the future phone insurance ftw.
