This application is designed in a way that allows its integration with other systems or its modification to perform other functionalities:

 

• It can be integrated with other systems performing the same functionalities for other types of cell phone or other Nokia series

• It can be modified to make the cell phone the side that receives the SMS and routs it over Bluetooth to the PC, where the phone here becomes the master and the PC becomes the slave.

• The application may be allowed to import the contacts stored on the sim card when Nokia 9500 becomes a supporting phone to JSR 177 or SAP. JSR 177 is the "Security and Trust Services API" (SATSA) for J2ME which is necessary for accessing the sim card. This API is not currently supported on Nokia 9500, so the application is able to retrieve contacts stored on the default cell contact database. SAP, which stands for "SIM Access Profile", is a Bluetooth profile that allows accessing the SIM card. The SAP is not supported on Nokia 9500 either.

• The application running on the cell phone can be signed in order not to keep asking for user permission to access protected APIs. Each time the application calls a protected library, a security prompt will be displayed asking for permission. Also, the installation of unsigned MIDlets gives a warning about the un-trusted nature of the software, but when installing a signed MIDlet, no warnings are given.
