Hi, I'm trying to find a qay to uniquely identify a device that is not tied to the SIM card. That is, some sort of serial number or device identifier that will be different between two phones and will not change if the user swaps SIM cards. TelephonyManager.getDeviceId() and .getSimSerialNumber() won't work, as they are tied to the SIM card. BlackBerry has DeviceInfo.getDeviceId(). Does something like this exist in Android?
