I accidently spilled milk on my iPhone 4

I tripped with a bottle of cereal and spilled it on my iPhone 4 (not to the point where my iPhone was drenched) I tried to clean it off as much as I can for about 30 seconds. Then left it alone for a minute. (This was all under panic) After that i shut it down, turned it on, I noticed that it was twitching alone the edges of my iPhone, and on the side of my background image. I turned it off again and waited while I was going paranoid. After that I turned it on again and texted my boyfriend to tell him somethings wrong and to call me on my house phone (he has experience with Apple) I turned off my passcode incase I couldn't log back into my phone. Now I have it in a bag filled with rice. It has been in there for about maybe 2 hours. I went to go check up on it and the twitching stopped, but within 2 seconds later it started again.

Any advice?

Turn it of and DON't turn it on for th next 24 hours. Don't blow dry it.

Put it in rice overnight.
