In the fall of 2009, my iPhone 3G decided it didn't want to do WiFi anymore. Unlike many people who can't connect to WiFi, it simply can't see ANY WiFi networks. It has been able to see WiFi TWICE since then. Once was in December, at my girlfriends apartment one night. Next day, couldn't see it. Today (right now) is the second time the iPhone decided to see the WiFi in my house. I have no idea what is going on. I've tried resetting it a million times, I've erased and reinstalled the OS, etc. Nothing seems to work. This is twice now, totally out of the blue. It's never been hacked, modded, or unlocked. It's all stock. However, I did have some water damaged over a year ago. I dropped it in the toilet in the spring of 2009 (don't ask). However, I left it in a bowl of rice for a week and it was fine for months. Since the water markers show no warranty. Any ideas?
