My iPhone fell in the toilet! - 2

Okay so my iPhone fell in the toilet two days ago and I took it out right away and it worked fine until today. The screen had lines on it and now it won't work. Every time I press the button on the top right, lines show up on the screen. I tried plugging it in my computer but nothing came up. I wanted to know if I can still access my data or transfer it to my Ipod. Will my pictures still be saved? How much will it cost to replace it? Oh and it's in rice right now. Will that help in anyway?

So I play candy crush on my iphone… Not through facebook. Which means I don't have friends on candy crush. About two weeks ago, another icon sat next to mine and I don't know who it is… When I pass a level, this person passes the level too… And the individual gives me extra life as well… It creeps me out because I don't know who it is… I almost feel like I'm being stalked. Has this ever happened to anyone?
