Can record stores be shared between MIDlet applications?
In MIDP1.0 (which is the most widely-supported version at present) MIDlets can read and write record stores created by other MIDlets in the same MIDlset suite (that is, deployed in the same JAR file). MIDP2.0 adds support for shared record stores: when a record store is created, the creating application can specify whether its record store is to be accessible to other MIDlet suites or not.
