A method includes providing a programmable device, such as a mobile phone, having a plurality of operational modes and a key data, and providing a computer system having configuration data corresponding to the plurality of operational modes. An authorized portion of the configuration data corresponds to the key data and to at least one authorized operational mode of the mobile phone. The method further includes sending the key data from the mobile phone to the computer system over a data connection, then, activating the authorized configuration data at the computer system referencing the received key data, before finally, programming the mobile phone with the authorized configuration data through the data connection to enable a predetermined authorized operational mode. Protection from errors in programming and device cloning is insured, as the computer system is prevented from programming the mobile phone until receiving the key data from the mobile phone.
