RIM passed a CDMA device called the RCL21CW through the FCC today.  Label-placement pics of the device show Curve branding, so this looks like it will be a new version of the Curve for either Sprint or Verizon.  The test report indicates that the device will have 800/1900 CDMA/EVDO as well as WiFi and Bluetooth, but that’s all we know for now.
