Abstract: An improved handheld electronic device has a display and a keypad, with the keypad being movable among a number of configurations that enable the “real estate” occupied by the keypad to be increased or decreased, and to correspondingly enable the viewable area of the display to be relatively decreased and increased, respectively. In one aspect, a first keypad portion and a second keypad portion can be disposed substantially coplanar when the keypad is in a first position and disposed noncoplanar when in a second position. In another aspect, a device can include a keypad and a flexible sheet-like piece of covering material structured to overlie a display, with the keypad and the piece of covering material being connected together.

Abstract: A system and method for configuring access to an electronic mailbox based on limited configuration parameters received from a user. A database stores configuration conventions for a mail domain. A mailbox interface module receives configuration information from a user that is limited in the configuration parameters required for accessing the electronic mailbox. The module retrieves configuration conventions for the mail domain from the database and generates sets of potentially valid configuration parameters based on the retrieved configuration conventions and user supplied configuration information for accessing the mailbox.

Abstract: A processor-implemented method of managing communications to contacts from a mobile device includes storing a list of contacts, associating with each contact one or more communication modes, and associating with each contact a communication profile defining one or more preferred communication modes from the one or more communication modes. Upon indicating an initiation of a communication to the contact, a preferred communication mode from the communication profile is selected to communicate with the contact.

Abstract: Methods and apparatus for limiting communication capabilities in mobile communication devices are disclosed. In one illustrative example, an operating variable of a mobile communication device is detected to be within one of a first range of values, a second range of values, and a third range of values. The mobile device operates in a full communication state if the operating variable is detected to be within the first range of values, a first limited communication state if the operating variable is detected to be within the second range of values, or a second limited communication state if the operating variable is detected to be within the third range of values. When receiving a communication request for establishment of a voice call or for communication of a user data message, the mobile device permits or prohibits the communication depending on the communication state, and preferably depending on whether the communication request is for a non-emergency or emergency communication.

Abstract: A system and method for packaging electronic messages for delivery to a communication device is provided. Where the electronic message comprises at least one quoted parent message, the quoted parent message is identified by means of delimiters within the body of the electronic message, and the quoted message thus identified is replaced with an identifying instruction referring to an identifier corresponding to a previously received message comprising the quoted parent message. The edited electronic message is then transmitted to a recipient device, which uses the identifying instruction to reconstruct the original message by querying a data store using the identifier to locate a copy of the quoted parent message. If no quoted parent message is found, a request is issued by the recipient device to transmit a full version of the original electronic message.

Abstract: Methods and apparatus for efficiently managing the storage of e-mail message information for a mobile station are described. In one illustrative example, a plurality of e-mail messages are received by the mobile station through a wireless network and stored in memory. If a size of the e-mail messages reaches a predetermined limit of the memory, e-mail message bodies of some of the e-mail messages (e.g. relatively “old” e-mails) are automatically deleted from the memory while e-mail message headers of the e-mail messages are retained. E-mail message headers of e-mail messages having deleted e-mail message bodies may still be visually displayed in a list at the mobile station. Subsequently, if a user selection of one of these e-mail messages in the list is identified, an e-mail message body of the e-mail message is requested by the mobile station and received from a server through the wireless network.

Abstract: A scheme for redirecting data items to a user of a mobile data communication device that is associated with a host system and communicates therewith via a wireless network. In one embodiment, a method comprises: detecting arrival of data items for a user at the host system from one or more senders, the data items being directed to an address associated with the user at the host system; determining a delivery level provisioned for the user at the host system; and responsive to the delivery level, applying a delivery rule with respect to the data items received for the user to bundle at least a portion of the data items for transport in a single transmission to the user via the wireless network.

Abstract: A scheme for message folder synchronization. In one embodiment, a method may comprise: automatically detecting arrival of a message at a messaging server for a user; storing the message in a first folder of a first folder system associated with the user at the messaging server; processing at least a portion of an instance of the message for transmission to the user's mobile data communication device over a wireless network; receiving a status signal from the mobile data communication device indicating that the message has been moved from a first folder at the mobile data communication device to a second folder of a second folder system associated with the user at the mobile data communication device; and responsive to the status signal, moving the message from the first folder of the first folder system at the messaging server to a second folder thereat corresponding to the second folder of the second folder system.
