Iphone 3GS dropped in toilet

Okay, so I dropped my iPhone 3gs in the toilet, but grabbed it out in about 2 seconds. I used a hair dryer on it on a VERY low heat held away from the phone. Then it was put in rice for 36 hours. After this, I took it out and tried to turn it on. Nothing. I put it back in the rice for a day and then plugged it in. After about 4 hours of plugging in it powered on showing me my lock screen. It asked if I wanted location services and then said to connect to itunes. It powered off, and I tried to turn it on again but it would only show the apple logo before going blank. I have tried to turn it on a couple times throughout the day (no joy). When I dropped it in the toilet it had 32% battery life but when it powered up while plugged in it showed 100%. I have now plugged it into my Mac but iTunes doesn't recognize it. However, the iPhone is showing the apple logo for about 15 seconds before going black repeatedly. There's a sort of crinkled effect (like when you let a magazine get wet and it dries funny?) on the screen. Has the battery fried? Is there something wrong with the screen? Is there anything i can do to help it or should i put it back in rice and hope for the best?

Just buy an iPhone 4 it's only $99
