On BlackBerry platform before installing the actual PrivateGSM application you should download and install an "installer" application that checks if you device is supported or if it could be supported after an OS upgrade (eg: Bold 9000 or Curve 8520 has by default an operative system version of 4.6.x which is not supported, but if you upgrade the OS through Desktop Manager to OS 5.x, PrivateGSM will work on these devices).
