Ipod Touch Went Through washing Machine

So my ipod touch went through the wassh but not the dryer. I know, it was really stupid. So, i put my ipodd in a bag of rice for a week and it seemed to absorb all the water out of the screen. The ipod looks like it is in perfect condition.

however, It only turns on if it is plugged in with an old ipod cable, going through firewire. As soon as i unplug it, it turns off. for a while, it connected to my itunes but ever since i reset it, it hasn't. Another problem is when i go to general setting it says i have "No WI-FI"

I don't have extended warranty. is it time to say goodbye to it or is there anything i can do?
