My iphone was dropped in a coke cup

Take it to an AppleStore.

I would recommend not taking it to the Apple store. If the done and headphone jack are working fine. What they will do is " brand" your serial number in their system so if you ever bring the handset in for a real problem, they'll say it was caused by the liquid
damage.

Is the moisture indicator tripped?

My edit option was disabled ony last post ?!?!

What I meant to write is that if everything working OK right now, don't take it to the Apple store, as any future issues will be blamed on the liquid damage. If things aren't working like they should, then the Apple store may be your only option. Just be sure to be very polite and they may just replace it for you, but no guarantees.

The Edit option has a timeount. If you wait too long you cannot edit your post.

Drop it in a cup of Pepsi. It should remedy any issues.
Sorry in advance....I couldn't help myself.

Yes, it is water damaged. It may work fine or it may not.
