My Nano 3g is going crazy. It constantly gets a white screen, I have to reset it about 5 times for the Apple logo to appear, then when the menu comes up it works for about 30 seconds and then the screen starts distorting liek crazy and the color change really weird until it's totally unviewable. I tried restoring it and nothing happened. What should I do? I'm in Mexico so I can't really go to any Apple Store until the summer, and my warranty expires in June.
