Example program to retieve IMEI number and model name.

The IMEI number (International Mobile Equipment Identity) is a unique 15-digit code used to identify an individual GSM mobile phone in a GSM network.

The IMEI number can be displayed on most phones by dialing the code *#06#. For example, when dialling this key sequence in the phone application on a W950 phone, the following IMEI number might be displayed: 00460101-869342-5. Every phone has a unique IMEI number, which is usually printed under the battery on the phone.

The IMEI number is used in many mobile applications since the unique number makes it possible to lock software to a particular phone. This effectively prevents unauthorized copying of an application. The application sis file can be copied, but the application can not be used on phones for which there dose not exist a valid licence, which must be bought from the application manufacturer.
