I dropped my iPhone in the toilet

Halayna Scott, skip the rice. It does not do anything. It will not fix your phone and it will not stop corrosion. Using rice is the equivalent of doing nothing. All it does it gives a false sense of security. The very first thing I suggest is that you stop using the device, (remove the battery) and totally disassemble it, follow the guides on here. Then clean it with +90% isopropyl alcohol. This will displace the water and stop corrosion. It it okay to submerge a board in isopropyl alcohol. Here is a guide for that. Even so it was written for a 3G, the procedure is still the same. After that, air dry all the components. Do not forget to clean the connectors on the board as well as the cables. Then re-assemble with a new battery This is not optional but a must to avoid failure later on. " Check your board for any missing or damaged component. Water damage is the toughest to trouble shoot and to repair.
