Okay, so normally, I sync my iPhone to iTunes on 2 PCs. On one PC, we have the account where we have all the music and apps and things. That is my wife's computer. Then, on my own computer, I usually sync it to iTunes with the only reason being to get my pictures. But for some reason, all of a sudden, after updating iTunes to the latest version, when I plug in my iPhone, it doesn't recognize it or anything. It's as if it isn't even plugged in. Any ideas?
