Widely recognised as one of the better anti-theft apps on the Android Market currnetly, Cerberus are celbrating 100,000 paying customers by giving away licences to those who sign up before the 29th of Feb.
The app installs to your phone and once granted superuser permissions it has the access it needs for you to be able to do everything from tracking it’s current location, retrieving call and sms logs to taking a screenshot or photo of whatever the camera can see at the time.
Having used this for a couple of years now and recovered a lost phone due to it’s installation: I’d recommend you download it and register your details for the lifetime licenced account here.
