The persistent store net.rim.device.api.system.PersistentStore works, and is good for data you wish to persist across different invocations of the application.
The runtime store net.rim.device.api.system.RuntimeStore allows sharing of runtime state between applications without the constraints required to persist the data.
The RMS store javax.microedition.rms.RecordStore can also be used for sharing and persistence, doesn't need the RIM application signing key, and is portable to other J2ME devices.
