MerrySpy is a new spy software used to control and monitor mobile phones silently. An ordinary Nokia S60 mobile phone that is installed with MerrySpy will become a spy phone at once which acquires the following features: Record every voice call automatically, then pack and save the most recent recorded call clips in a single enciphered file. Answer the call from a predefined telephone number silently, then play recorded call clips to the line repeatedly, so that you can listen to the recorded voice calls remotely one by one, over and over again. Answer the call from a predefined telephone number silently, then keep silent so that you can monitor the sounds surrounding the spy phone. Make a voice call secretly upon a command from a remote phone. Forward all SMS messages, receiving and sending out, to a predefined telephone number instantly. Send call logs to a remote phone. Send address book to a remote phone. Notify a predefined telephone number by sending it a SMS message if the SIM card has been changed. MerrySpy hasn't any visible user interface, it is tiny (less than 60KB) and unnoticed. MerrySpy works in an imperceptible manner, all the above actions do not make sounds, vibration, backlight, alter the screen display, or leave logs. You can install MerrySpy yourself at home within several minutes. After installation you don't need to touch the spy phone any more, you will control the spy phone remotely by sending it SMS commands which are undetectable. In a word MerrySpy is totally different from all other spy softwares, maybe it's the most powerful one!
