Rice is hit or miss but if you can (assuming you live in a home with a furnace) sit it up with the speakers facing down on an air flow register for about 10 minutes. The heat from the furnace will not harm the sensitive components and will dry the phone out nicely including the display layers. DO NOT USE a hair blower! The iPhone is capable of drying out much more easily than phones with removable backs as the iPhone while sumbermeged in liquid (for a short time) will take on limited moisture hence can be dried and keep on keeping on. My dauhter dropped her iPhone 5 in a toilet and it was fine after spending 24 hours in rice and 10 minutes on the air register while the furnace was producing heat.
One last thing. DO NOT POWER ON the phone until the drying out efforts have been completed and certainly DO NOT plug it in.
