IMPORTANT Due to this device being configured to work in the United States, there are two things that shouldn't be done with this device. First, your security PIN code should not be longer than 4 digits. Secondly, DO NOT factory reset. So far devices that have factory reset or have longer PIN codes become unusable. We are investigating the cause of this and hope to have a solution. However In the meantime, we ask you that you don't do those things. If you do, we cannot accept the device as a return.
