Re: i dropped my phone in water and now i cant connect to wifi,
Yep... best way to make that water damage permanent is to run that phone after a dunking until something breaks...
If you try the rice trick, open up anything you can (back, trays, etc.), remove anything you can (battery, cards, headphones, whatever).
Submerge the phone in rice. It should be completely surrounded. Seal it all in a bag or container. WAIT. Don't be in a hurry. There is no point to doing this half way. DON'T check every hour. You aren't cooking it. You don't have to "stir occasionally." I don't care what your buddy says. It NEEDS to stay in the rice about 72 hours (that's 3 FULL days) for maximum effort at drawing that moisture out of every crevice and cranny.
No guarantees at this point. As indicated above you may have done something in. You mixed electricity and water by running the phone after the submersion. This is never a good combination.
Good Luck.
