I would try to avoid referencing the entire BlackBerry Internet Service
environment as having a weakened security posture.  The actual problem here
is not in the hardware or software but in the wetware.  The device and
underlying framework do what they are supposed to.  The user is responsible
for making the bad choices.

Again, this is not a problem with the BlackBerry framework.  It is only due
to the fact that a user will allow access to permissions or ignore an
application's constant prompts for permission requests.  One approach would
be to flood the user with false requests for permission.  Then, given how
useful your decoy app is, a user will either continue to use the app or
discard it altogether.  If he continues to use it, then you can give him the
one option of "Grant me these permissions and I will leave you alone".  He
will most likely pick that option because he doesn't want his usage to be
disrupted and because he is conditioned to always say "Yes" to security
prompts.
