executing, at the processor of the mobile device, a message search of the e-mail messages stored in the memory of the mobile device to identify only e-mail messages having one or more attachments; and

for each identified e-mail message having one or more attachments:

determining, at the processor, whether an attachment of the one or more attachments has been previously opened based on the indicator associated with the attachment; and

displaying the identified e-mail message in the GUI on the display of the mobile device when the indicator associated with the attachment indicates that the attachment has been previously opened.

2. The method of claim 1 , wherein the each identified e-mail message is displayed in a search result screen in the GUI on the display.

6. The method of claim 3 , wherein the plurality of selectable options also comprises a second selectable option to search e-mail messages stored in memory of the mobile device to identify e-mail messages having one or more attachments that have not been previously opened.

7. The method of claim 3 , wherein the plurality of selectable options also comprises a third selectable option to search e-mail messages stored in the memory of the mobile device to identify all e-mail messages having one or more attachments.

8. The method of claim 1 , wherein each respective indicator indicates that the respective attachment has been previously opened when content of the respective attachment has been at least partially displayed on the display.

9. The method of claim 8 , wherein the attachment is stored in part, in the memory of the mobile device.

10. The method of claim 1 , wherein each respective indicator indicates that the respective attachment has been previously opened when content of the respective attachment has been at least partially played on a speaker of the mobile device.

11. The method of claim 10 , wherein the attachment is stored in part, in the memory of the mobile device.

12. A mobile device comprising:

a display configured to display a graphical user interface (GUI);

a communications subsystem configured to receive e-mail messages from an e-mail server via a data network and a wireless network, wherein at least one of the e-mail messages comprises one or more attachments;

a memory operably coupled to the communications subsystem and configured to store the e-mail messages received from the e-mail server;

a processor operably coupled to the display and the memory and configured to:

for each e-mail message that includes one or more attachments:

store, in the memory, an indicator associated with each respective attachment of the one or more attachments, each respective indicator indicating whether the respective attachment has been previously opened at the mobile device, each respective indicator indicating how much of the respective attachment's content has been previously opened when a respective e-mail associated with the attachment has been opened;

display a single selectable option in the GUI on the display to search e-mail messages stored in memory in at least one of an email server and the mobile device to identify only e-mail messages having one or more attachments which have been previously opened;

in response to receipt of an input indicating selection of the single selectable option:

execute a message search of the e-mail messages stored in the memory to identify only e-mail messages having one or more attachments; and

for each identified e-mail message having one or more attachments:

determining whether an attachment of the one or more attachments has been previously opened based on the indicator associated with the attachment; and,

display the identified e-mail message in the GUI on the display of the mobile device when the indicator associated with the attachment indicates that the attachment has been previously opened.

13. The device of claim 12 , wherein each identified e-mail message is displayed in a search result screen in the GUI.

14. The device of claim 12 , wherein the processor is further configured to display a plurality of selectable options in the GUI, the plurality of selectable options comprising the single selectable option.

15. The device of claim 14 , wherein the plurality of selectable options are displayed in a search screen in the GUI on the display.

16. The device of claim 15 , wherein the plurality of selectable options are displayed in a menu in the search screen.

17. The device of claim 14 , wherein the plurality of selectable options also comprises a second option to search e-mail messages stored in memory of the mobile device to identify e-mail messages having one or more attachments that have not been previously opened.

18. The device of claim 14 , wherein the plurality of selectable options also comprises a third option to search e-mail messages stored in memory in at least one of the email server and the mobile device to identify all e-mail messages having one or more attachments.

19. The device of claim 12 , wherein each respective indicator indicates that the respective attachment has been previously opened when content of the respective attachment has been at least partially displayed on the display.

20. The device of claim 19 , wherein the attachment is stored in part, in the memory of the mobile device.

21. The device of claim 12 , wherein each respective indicator indicates that the respective attachment has been previously opened when content of the respective attachment has been at least partially played on a speaker of the mobile device.

22. The device of claim 21 , wherein the attachment is stored in part, in the memory of the mobile device.

23. A physical computer-readable storage medium on which a plurality of executable instructions is stored, the instructions for performing a method of searching e-mail messages comprising one or more attachments on a mobile device, the method comprising:

more attachments on a mobile device, the method comprising:

receiving, at the mobile device, e-mail messages from an e-mail server via a data network and a wireless network, wherein at least one of the e-mail messages comprises one or more attachments;

storing, in memory at the mobile device, the e-mail messages received from the e-mail server;

for each e-mail message that includes one or more attachments:

storing, in the memory at the mobile device, an indicator associated with each respective attachment of the one or more attachments, each respective indicator indicating whether the respective attachment has been previously opened at the mobile device, each respective indicator indicating how much of the respective attachment's content has been previously opened when a respective e-mail associated with the attachment has been opened;

displaying a graphical user interface (GUI) on a display of the mobile device, the GUI including a single selectable an option to search e-mail messages stored in memory in at least one of an email server and the mobile device to identify only e-mail messages having one or more attachments which have been previously viewed;

in response to receiving, at a processor of the mobile device, an input indicating selection of the single selectable option:

executing, at the processor of the mobile device, a message searchof the stored e-mail messages to identify only e-mail messages having one or more attachments; and

for each identified e-mail message having one or more attachments:

determining, at the processor, whether an attachment of the one or more attachments has been previously opened based on the indicator associated with the attachment; and,

displaying the identified e-mail message in the GUI on the display of the mobile device when the indicator associated with the attachment indicates that the attachment has been previously opened.
