Step 1: Basically the only step
After you've done that:
Take your wet cell phone, and seal it in a bag containing two cups of long-grain, white rice.
In approx. 24-48 hours, your cell phone should have dried out completely.
However, you should check it periodically to see if it starts working earlier, but I still recommend you leave it the full time to insure that all of the moisture is removed.
