One of the major advantages with Blackberry spy software is that it operates under complete stealth. The person using the particular mobile phone in which the software has been installed will not get any doubt, whatsoever that he or she is being tracked. Once installed the software will secretly record all the activities of the particular handset and send it across to you. Software technology has advanced to such an extent nowadays that you can even get to hear real time conversations taking place on the mobile phone which is being spied upon.
