I went into the ocean with my iPhone 5c in my pocket for about 15 minutes. Help?!

Added (1). I've been doing the rice method since last night. If that doesn't work, I've read to open up your phone and manually get all the water out. I need some tips. I can't lose this phone, it's very important to me.

R.i.p

Firstly you need to open you iphone and take out the battery and the logic board. Then get alcohol and a toothbrush and clean your logic board. After that leave it in uncooked rice for 48-72 hours and assemble your phone back.
