Using your Blackberry web browser goto the download URL and download XShield onto your berry. Make sure you type in the exact case.
Note: If you already have XShield installed and just want to update to the newest version, make sure you back up all your XShield data before upgrading.
Initial Setup Instructions
Setting up your first passphrase
One of the first screens you will see will be a screen asking you to setup a passphrase. The passphrase is used to protect your data. It has to be at least 6 characters long. The longer it is, the more secure your data will be. Your passphrase can be changed at a later time but do not forget your current passphrase as it is required to decrypt your data.
Initialize the storage key
Although the Blackberry already has a random source generator, it was decided that this extra step should be taken to ensure true random number generation. Enter in 80 random characters or more and then click on the Initialize button to initialize the storage key.
