Contact list database
At least one contacts database is available in Nokia devices, but it is common to have two databases - one for the contact list in the main memory and another for contacts in the SIM card.
More databases might be available, depending on the device. These databases can be selected by name with the openPIMList(int pimListType, int mode, String name) method. The names used to identify the database correspond to the localized name used by the device, and it is possible in certain cases that they could even be user defined. Therefore, the name should not be hard coded in the application; instead, it should be obtained with the listPIMLists method. The order of the database names returned by the listPIMLists method is also the preferred order in the device. Commonly, there are two databases that may be used. The first is the "in-memory" database, which is used by default, and the second is the list in the SIM card. The approach to open the default database is to either call openPIMList(int pimListType, int mode) or pick the first entry from listPIMLists and call openPIMList(int pimListType, int mode, String name)
