For some reason, my Eris I think, has lost it. The problem is, that if the phone has a sudden jolt (or even if you move it sometimes), it will arrow down the selection (sort of like scrolling the ball down). If you keep shaking it, it will just keep going down until it can't anymore. I'm thinking its the accelerometer. But the catch is, it ONLY does it if I have a USB cable plugged in. Without the USB cable, it doesn't happen. It just showed up today. Its really bizarre. At first I thought it was a firmware bug, but in recovery mode, it still does it. Should I take it into Verizon or what?
