First of all, if this ever happens again, immediately get it out of the water and remove the battery and do not put it back until the phone is dry. If you run current through the phone after it's wet, you're more likely to fry the phone. I know it's hard to resist the temptation to see if your phone will power on after its gotten wet, but its best to turn it on only after its dry. With that being said, take the phone apart as much as possible, meaning take the battery out of the phone, remove the back door (if applicable) and dry the phone off with a towel. Then put all of the parts in a zip-top bag with dry rice in it. The dry rice will help pull the moisture out of the phone. Leave it in the bag a couple of days. Reassemble the phone and try to power it on. I hate to say it, but most likely your phone won't function properly, but hopefully you'll be able to get it to power up so you can get the phone numbers out. I have been fixing cell phones for a long time and typically when they start constantly vibrating and don't power on all the way (won't go to the main screen) they are goners. If you have a good third-party dealer that has a tech on staff and see if they will clean the phone out. Corporate stores typically will not do this for you because of the liability, but third party dealers don't have the same strict guidelines to follow.
