I was waiting for the OS fix they keep saying is coming and finally gave up and went out to the verizon again. Without hesitation they gave me a new phone after seeing the trackball issues. This one is great. Trackball is flawless and the battery door even stopped vibrating. Dont wait for the OS people, they are just trying to get you out of the store when they say that. How can to tours be running the same OS and one works perfectly while the other does not? Ill tell you how its the hardware. There was a bad batch and they are trying to get people to not return them. My opinion. Either way go get a new one.
