F-Secure offers Anti-Theft for Mobile to protect your contacts and personal files should your Symbian OS, Windows Mobile, or Android phone be lost or stolen. You can send an SMS message to lock your phone and keep it locked until you enter the correct password. You can use the locate feature to receive a message, sent to a designated phone number, with a link to the current location of your phone. If it looks like your phone won’t be returned to you, send a code to wipe out all your data from the phone. Finally, if someone replaces the SIM card in your phone, it can automatically lock down and send you the new phone number. The F-Secure Anti-Theft for Mobile software is a free download.
