Dropped iPhone 4 in water still works?

So I dropped my iPhone 4 in the toilet don't ask lol. Well as soon as it happened I turned it on and it stayed off with the the led light on and the phone completely off. So than I put it in a bag of rice cause I heard it drains out the water left in one for 3 days tried my phone this morning it works everything kinda lags but my question is since it still has 1 year warranty can apple replace it if I say it has like a touch screen issue? By the way I checked under the headphone jack thing and the color had not turned red for water damage still white so is that good? And if it helps I had a case on my phone when I dropped it lol so could of helped and thanks!

Depends on the warrenty.apple offeres severel.
If the warrenty you have says acceidental mishaps then yes a new one could be requested however most apple warrentys you will not get a new one because it was your fault not the prouducts,
Hope this helps
