haha, obviously you work in an environment where security is fairly important. I'd think you would respect that and maintain your phone's security features as installed.
You could always get an app for the user that touches the phone every 8 minutes, unless you're getting up and walking away from the phone, in which case the security is functioning exactly as it was designed.
Don't mess with it, its not worth your job or your company's security. That is unless you work for RIM, in which case, if you're looking to lose your job anyways, why not leak us some betas first.
