I love how the OP "assumes" that RIM has now magically stopped all uaers from ever accessing the dev account ever again.
The problem with 'security' is QNX is a Unix build made by another company. I love RIM but if after all of these years they still haven't stabilized or properly protected devices using their own OS (I showed them how I can pull your passwords, phone numbers, etc, off your locked phone via USB i. OS5/6/7 - and after several calls/emails/posts I still havent heard back) then how can the OP really believe RIM stands a chance at locking down a third-parties OS when they no longer have enough developers or time to even validate the code.
Point is, just because an exploit isnt available for the "one" person who broke every security lock on the PB so far (remember OP, RIM's security team - who is much more qualified than you on the subject, claimed it could never be done from the start) doesn't mean it is safe or unbreakable. It just means that the one amazing developer who has been working hard on it realizes the solution isnt what he needs and stable root would take more time than he has available.
In fact, now that DB has been opened to the public, RIM may be facing its biggest challenge yet as anyone who wants to contribute now can and data that was previously protected by him (things like taking purchased BARs) is now in the hands of the public .
But yeah, Im sure you made some comment somewhere in the past that you thought was important and correct (when really, it was neither) and has placed you in an abstract position of ignorance about the safety of your device. Hackers love people like you You should *never* put blind faith in security on a device unless you wrote the code yourself.
