A message exchange network is disclosed in which at least two different methods of storing messages in memories of message storage entities, e.g., a mobile handset, an SMSC, an e-mail client, or an e-mail server, are utilized based on the type and the content of the information contained within the message. An information service message containing information that is supercedingly updateable, e.g., stock quote, weather or traffic information, is stored using a replacement method by which an older message previously stored is replaced by a newly received message. All other types of messages are stored using an append method by which the newly received message is stored in an unoccupied available memory location. In a disclosed embodiment, message identifier included in the message itself provides information necessary to distinguish between the aforementioned two types of messages. In a disclosed embodiment, a block of message identifiers is reserved for storage of information service messages. The architectures and methods for receipt, delivery and storage of messages disclosed herein replaceable and/or on demand update of information service messages while providing efficient use of memory in which the messages are stored, avoiding the annoyance and inconvenience to the subscriber in having to scroll through numerous stale and/or obsolete messages in order to view the most current up to date message and having to manually selecting and deleting obsolete and stale messages, and avoiding unnecessary deliveries of the obsolete and stale messages by message centers.
