Method, apparatus and system for searching email messages with attachments at a wireless communication device

摘要

A set of email messages is received at a wireless communication device. Each of the email messages has at least one attachment. For each attachment, an indicator of whether any content of the attachment has been presented at the wireless communication device (e.g. displayed on a display or played on a speaker) is maintained. A subset of the set of email messages is identified and displayed on the basis of the indicators and a user-specified parameter, which may be specified via a graphical user interface. One value of the parameter may cause only email messages having at least one attachment whose content has been at least partially presented at the wireless communication device to be identified. Another value may cause only email messages having at least one attachment but having no attachment whose content has been presented in whole or in part at the device to be identified.
