I dropped my iPod touch into some water earlier today. Got it out immediately. Everything was working fine. But now the lock button isn't functioning properly. It never locks (except for auto lock when kept idle) and if I push the button a bunch of times occasionally it will ask me to slide the slider to power off. I bought this off eBay about a month ago. It's 2nd gen, which came out a few months ago. Is there a warranty? This device just came out, it's under a year old. Any help appreciated. Thank you.
