Just dropped iPhone 4 in water..

...and everything is working fine, but the dock connector is a little finicky. The speaker was previously playing half the volume displayed on the slider, but drying it out and rebooting fixed that.

Now, when I try to play anything through the speaker, the phone thinks it's connected to a dock and is playing all sounds (system and music) through the non-existent dock. It is off and on though; sometimes keyboard clicks and music will work for a few seconds and then flip back off.

The phone is an iPhone 4 GSM, unjailbroken. It is not on warranty or Apple Care either. Will I need to replace anything?

Corrosion is a ticking time bomb. It could start out minor but cascade eventually. Or it could end up clearing up on its own, its hard to say one way or another. You should avoid using the iPhone for at least a couple days to give it enough time to dry. As to having to replace anything, it depends on how comfortable you would be opening up the phone, and how willing you would be to trust a 3rd party to open it up and replace individual components. Or you could take it to Apple and pay up to replace it out of warranty or see about upgrading through your wireless carrier if you're eligible for a newer phone.
