1. A method of indexing, retrieval and managing of stored messages using a meta-data approach in a portable communication device, comprising the steps of: receiving a new message signal containing a new message and storing said new message with an assigned identifier in a message storage area of said portable communication device along with N previously received and stored messages with corresponding N identifiers; determining meta-data for said new message and storing said meta-data by a meta-data determining storage module of said portable communication device; and performing indexing of said meta-data and adding said indexing to M existing index hierarchies by an index determination and storage module of said portable communication device, said M existing index hierarchies are pre-defined for said portable communication device and said N previously received and stored messages are indexed in said M existing index hierarchies using their corresponding meta-data by said index determination and storage module, thus facilitating effective retrieval and management of the N+1 stored messages by a user based on said M index hierarchies and said N+1 identifiers, wherein N is zero or an integer of at least a value of one and M is an integer of at least a value of one.
