Is my iPhone gonna be okay now after the water?

Ok so march 15th about 75 days ago I dropped my brand new iPhone 4 in a pond. I fell in and my phone was in my pocket. I did the rice and had a blow dryer up to it. The head phone has the red dot as well as the bottom and apple said it was waster damaged. But my phone still works perfect 75 days later. The only thing wrong with it is when in brightness settings if you put it all the way down the screen goes black. Will it be okay now?

Once the connectors completely rust, it will be shot.
sell it as soon as possible

I dropped mine in water, soaked it in rice and it worked perfect. It really just depends. Seems like you answered your own question though, it's fine besides the screen brightness.

No one knows what kind of damage was done to your phone, not sure why you think a messageboard would know this.
