Know someone you hate who happens to use a BlackBerry? Annoyed by those BlackBerry carrying Canary Wharf city slickers who earns and spends too much money and also happens to drive a SUV?
Well, send them a long meeting request with bunch of texts in the location field and set the time in the past and it will cause their device hard reset thus losing their important client and boss e-mails.
Of course I am not suggesting you to do this. ;) Okay... maybe to those 4x4 owners.
BlackBerry users who is keen to protect themselves from such attacks ought to update their software to version 3.8 or 4.0.
