I dropped my IPhone in the toilet, and now my home button doesn't work?

2 days ago I dropped my IPhone 4 in the toilet, and pulled it out right away. I dried it off quickly and it was perfectly fine and nothing was wrong. But then last night, my home button started to not work unless I pressed it 10+ times… I have the accessible touch thing on, but I was wondering if could fix this myself?

Sorry, but your iPhone is ruined. Your parents will go ballistic when they find out that the gadget that they spend so much money on for you is now destroyed. They will be like, "How could you be so careless and irresponsible to take that thing into the bathroom with you?!".

You could call apple and they might be able to fix it for you. But if you want to fix it at home, you should call someone who's good with technology to come look at it.

Its ruined, and will get worse in the next few days, sell it for parts.
apple will not fix or replace water damaged iphones.

Unfortunately I think you are going to have to get a whole new phone. The 4 and 4S are designed so that they can't really be repaired. My lock button on my phone just wore out from heavy use, and just to get the one button fixed I had to get a whole new phone, however I did not have to pay full price for the replacement. Go to your local Apple store and see what they can do for you. They are pretty good about things like that. But as far as doing anything yourself about it, I do not think that there's anything that you can do.
