What's wrong with this?
I've been gone from my house all day. When I got home, I went to plug in my iPod Touch 4th Generation, and it wouldn't charge. My sister's iPod is doing the exact same thing. She has the same kind of iPod and we have two separate cords. Last night, they were charging fine. I've tried taking out the cords and plugging them into different USB ports but nothing works. I charged my iPod at a different house and cord. Is it my cord, or my computer? How can I fix it?
