The way i have solved this before is:
By simply placeing the phone in a bag of rice (obviously not cooked)
the rice seems to absorbe the water in the phone well and provided my phone with a fix, however the screen showed what seemed like snow for three days and then went.
I also then took the phone apart and did the process again as to some how hope it would not rust.
hope this helps
the process is best done over night or for longer
