The chinese are well known in phone design copying, but they did it well with the Tianyu B832 phone.

Other than the usual multimedia features like media player, camera and FM radio receiver, the Tianyu B832 let you lock down your phone when it is stolen. You can first input up to 5 phone numbers to the notification list, if the phone detected a different sim card, it will send a sms to the phone numbers with the sim card detail. You can then make use of the phone number and get the subscriber detail from the telco. You can also reply the sms to issue a command to lock down your phone. Now at least you have disabled the phone, protect your data, although it is still no guarantee to retrieve back your phone!
