3. The handheld electronic device of claim 2 , wherein in response to receiving the input from the user, the display element includes a second dependency indicator providing an indication that the file displaying or executing in the second display portion corresponds to the display element displayed in the first display portion and identifying the file attached to the selected message.
4. The handheld electronic device of claim 3 , wherein the second user interface screen portion includes a navigational function button configured to receive navigational input, and in response thereto, navigate between hierarchical screens of the multi-screen email client.
5. The handheld electronic device of claim 4 , wherein the instruction sets further cause the microprocessor to:
receive a navigational input from the user at the navigational function button on the second user interface screen portion; and
move, in response to receiving the navigational input, the second user interface screen portion off of the first display portion and onto the second display portion and move the first user interface screen portion onto the first display portion.
6. The handheld electronic device of claim 5 , wherein any screen of the multi-screen email client displayed in the first display portion is always a parent window to any other screen of the multi-screen email client that is displayed in the second display portion.
7. The handheld electronic device of claim 6 , wherein the first display portion and the second display portion are in a portrait orientation, the portrait orientation defining a long dimension and a short dimension of each display portion, and wherein the first display portion and the second display portion are disposed side-by-side and adjacent to one another along the long dimension of each display portion.
8. A method of operation of a multi-screen email client, the method comprising:
executing the multi-screen email client on a handheld electronic device having at least a first display portion that is a first display device and a second display portion that is a second display device, distinct from the first display device, wherein the second display portion is separated from the first display portion by a hinge disposed therebetween, the hinge configured to allow pivotal movement between the first display portion and the second display portion;
displaying a first user interface screen portion on the first display portion, the first user interlace screen portion corresponding to a first screen of the multi-screen email client, the first screen including an identification for one or more messages received by the multi-screen email client;
displaying a second user interface screen portion on the second display portion, the second user interface screen portion corresponding to a second screen of the multi-screen email client, the second screen including a detail view of a selected message from the one or more messages, wherein the detail view includes a display element identifying a file attached to the selected message;
receiving an input from a user at the second display portion corresponding to a selection of the display element identifying the file attached to the selected message while displaying the first screen of the multi-screen email client on the first display portion; and
in response to receiving the input from the user at the second display portion:
moving the first user interface screen portion off of the first display portion;
moving the second user interface screen portion off of the second display portion and onto the first display portion; and
displaying or executing the file in the second display portion.
9. The method of claim 8 , wherein prior to moving the first user interface portion off of the first display portion, the first user interface portion includes a first dependency indicator providing an indication that the detail view corresponds to the selected message.
10. The method of claim 9 , wherein in response to receiving the input from the user, the display element includes a second dependency indicator providing an indication that the file displaying or executing in the second display portion corresponds to the display element identifying the file attached to the selected message.
11. The method of claim 10 , wherein the second user interface screen portion includes a navigational function button configured to receive navigational input, and in response thereto, navigate between hierarchical screens of the multi-screen email client.
12. The method of claim 11 , further comprising:
receiving a navigational input from the user at the navigational function button on the second user interface screen portion; and
moving, in response to receiving the navigational input, the second user interface screen portion off of the first display portion and onto the second display portion and move the first user interface screen portion onto the first display portion.
13. The method of claim 12 , wherein any screen of the multi-screen email client displayed in the first display portion is always a parent window to any other screen of the multi-screen email client that is displayed in the second display portion.
14. The method of claim 12 , wherein the first display portion and the second display portion are in a portrait orientation, the portrait orientation defining a long dimension and a short dimension of each display portion, and wherein the first display portion and the second display portion are disposed side-by-side and adjacent to one another along the long dimension of each display portion.
15. A non-transitory computer readable medium comprising:
a multi-screen email client executable by a processor of a handheld electronic device, wherein the handheld electronic device comprises at least a first display portion that is a first display device and a second display portion that is a second display device, distinct from the first display device, separated by a hinge disposed therebetween, the hinge configured to allow pivotal movement between the first display portion and the second display portion, and the multi-screen email client, when executed by the processor of the handheld electronic device, causes the handheld electronic device to:
display a first user interface screen portion on the first display portion, the first user interface screen portion corresponding to a first screen of the multi-screen email client, the first screen including an identification for one or more messages received by the multi-screen email client; and
