Application Management

If the user decides to save the data from the current MIDlet, the data will be preserved during the upgrade and the data will be made available for the new application. In any case, an unsigned MIDlet will not be allowed to update a signed MIDlet.

Installation and Deletion Status Reports

The status (success or failure) of an installation, upgrade, or deletion of a MIDlet suite will be sent to the server according to the JSR 118 specification. If the status report cannot be sent, the MIDlet suite will still be enabled and the user will be allowed to use it. Upon successful deletion, the handset will send the status code 912 to the MIDlet-Delete-Notify URL. If this notification fails, the MIDlet suite will still be deleted. If this notification cannot be sent due to lack of network connectivity, the notification will be sent at the next available network connection.
