My Ipod touch recently fell into water, but once dried, it worked with seemingly little to no problems. Today, after working for at least an hour, the screen froze and is now not working, but the sounds are still functioning.

Question

I accidentally dropped my Ipod into the lake, at the beach yesterday, but i caught it early and it wasn't too soaked... i wiped it off for the most part, and most of the buttons and the screen worked fine! i was shocked, and there were a few glitches with the camera and the slide button on the lock screen, but otherwise it was greatly intact! so i gave it a rest, put it in my purse, and picked it up fifteen minutes later, and it was working 100% normally again! when i got home a few hours later, i put it in rice for a few hours, taking it out every once and a while to check my notifications... it still seemed to be working perfectly, so i just set it down out of the rice, assuming the moisture was gone. this morning, again, everything was working normally, no glitches, UNTIL, i opened my instagram app, and the screen froze, and it seemed like it had two separate screens, and i held the Sleep button down until the screen went black... then i tried turning it back on, etc. and it still didn't work, and so i plugged it into the computer, holding down the sleep and home buttons, and itunes identified it as in recovery mode, and started updating. i tried again to press the sleep and home butttons, maybe pressing only the home button, because I heard the Siri noise, as well as the charging sound, but the screen was still black.... i checked my iTunes, and lo and behold, it had identified my iPod, and synced it to the computer, as if it were normally functioning. However, the screen is still not working, and Siri is not working either. The sounds may be the only thing that's functioning. Should i send it in?
