Waterdamaged iPhone not recognized by iTunes when trying to restore

Hi,

About a week ago, I was at soccer practice when it started to rain hard. My iPhone was in my bag and the water got through my bag, wetting the iPhone. When I got home, the screen was still on, so I turned it off and used a dust cleaner to get some water out of most of the holes. After that, I put it in a bowl of dry rice for about 48 hours. When I took it out, it had started to work again, but the home button didn't function properly. Then, about 2 days ago, the screen just turned black. It only worked when I had it plugged in, charging, and even then, there was no 3G connection or Wifi available. This kept on going, if it was plugged out, there was only a black screen. I then tried to restore it, but when I clicked restore, after 30 seconds, iTunes said there was an error 2001, or 21. Now my iPhone's screen is black, but if I click the power button, the apple logo starts up, then turning to the "Connect to iTunes" Screen. Is there any way to fix this?

Thank in advance!
