Mobile Defender - Designed to protect your hand-held device from malicious use. It supports all Windows Mobile 5 and 6 powered mobile devices. In case of lost or stolen, send an SMS with pre-defined content and Mobile Defender will wipe out all user information. You choose what part of the mobile system is important for you: Personal Contacts stored on SIM card or Appointments or files and directories on SD Card or device's non volatile memory. Even you can completely shutdown the system so no one can use it.
Mobile Defender will automatically find all non volatile memory so they can be cleaned up from sensitive data. There is option to Make Device Unusable. If used, only factory default reset can bring it into working state. Sometimes to preform this can be very tricky process involving in most cases contact with device's manufacturer and possessing a prove of purchase. Mobile Defender works as transparent and silent gateway hidden into device's operating memory.
Version 1.2 adds VGA device support, SIM Memory Clean-up, and extra Clean up features.
