Blackberry: Remove IT Policy

Whenever you purchase a second hand Blackberry either from eBay or from a friend, some of them have IT policy still attached to them. IT policy can be a hassle since most of it won't allow installation of 3rd party applications and such. The following are the steps to remove an IT Policy easily (compilation of sources from the internet):

First you need several files ready first:
  • Blackberry Desktop Manager (comes with the CD or download here)
  • JL_Cmder, a compilation of batch scripts by d_fisher from Blackberry Forums for some cases. For 8110, 8120, 8130 and 8330 with 4.5 OS installed simply use JL_Cmder resetfactory option, restart device and you're done.
  • BlackBerry default blank IT Policy and save it into your BlackBerry installation directory (c:\Program Files\Research in Motion\Blackberry (for other than mentioned above).
To remove the IT Policy, use the following procedure:
  • On Windows XP or Vista, go to regedit (Start>Run)
  • Navigate to HKEY_Current_Users\Software\Research In Motion\BlackBerry\PolicyManager and right-click your mouse and select New/String Value and name it as "Path". Then double click the "Path" and set Value Data to "c:\Program Files\Research In Motion\BlackBerry\policy.bin"
  • Open the Desktop Manager
  • Connect the Device
To verify that the IT Policy has been completely removed, in your device go to Options>Security and check reference to IT Policy and go to Options>Status and type BUYR and now you should see time and data usage instead of IT Policy.

EDIT: for 8310 use JL_Cmder works as well.

Good Luck!
