Um, NO. Please read the first post. This procedure is NOT for those who are on a BES who want to "get around" the IT policy. There is NO way to have a BB on a BES without that BES's IT policy. If you remove it you are removed from the BES. The policy will be replaced if you reconnect to the BES.
This procedure is for those who are removing their device from the BES or got a device used with a leftover IT policy.
