System and method for breaking up a message thread when replying or forwarding a message

1. A communication device comprising a processor and memory coupled thereto and a communication sub-system coupled to the processor for communicating over a network, the memory storing instructions and data for execution by the processor to configure the device to:

receive a message thread at a first device, the message thread comprising a plurality of sub-messages, each of the plurality of sub-messages being delineated from one another within the message thread;

receive input to compose a new sub-message associated with the message thread, the new sub-message indicating a first and at least a second sub-message recipients;

at a selection interface,

create a first modified message thread by selecting a first subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom; and

create at least a second modified message thread by selecting a second subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom, ones of the sub-messages comprising the selected first and second subsets being delineated by a respective sub-message header, the sub-message header determinable by parsing text of the message thread, the first and at least a second modified message threads comprising the new sub-message; and

initiate communication of the new sub-message, the first modified message thread communicated to the first sub-message recipient, and the at least a second modified message thread communicated to the at least a second sub-message recipient.

2. The device of claim 1 wherein the device is configured to automatically delineate each of the respective existing sub-messages.

3. The device of claim 1 wherein the existing sub-messages that are not included in the modified message thread are replaced with a removal indication.

4. The device of claim 1 further configured to initiate communication of the modified message threads to a second device by one of replying to a sending device of the message thread, replying to the sending device and all recipient devices of the message thread and forwarding the message thread to at least one device.

5. The device of claim 1 wherein the modified message threads comprise at least one attachment, the device is further configured to receive an optional selection of an attachment for inclusion in the modified message threads.

6. A method of communicating a message thread comprising:

receiving a message thread at a first device, the message thread comprising a plurality of sub-messages, each of the plurality of sub-messages being delineated from one another within the message thread;

receiving input to compose a new sub-message associated with the message thread, the new sub-message indicating a first and at least a second sub-message recipients;

at a selection interface,

creating a first modified message thread by selecting a first subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom; and

creating at least a second modified message thread by selecting a second subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom, ones of the sub-messages comprising the selected first and second subsets being delineated by a respective sub-message header, the sub-message header determinable by parsing text of the message thread, the first and at least a second modified message threads comprising the new sub-message; and

initiating communication of the new sub-message, the first modified message thread communicated to the first sub-message recipient, and the at least a second modified message thread communicated to the at least a second sub-message recipient.

7. The method of claim 6 wherein delineating each of the respective existing sub-messages is performed automatically.

8. The method of claim 6 wherein the existing sub-messages that are not included in the modified message thread are replaced with a removal indication.

9. The method of claim 6 wherein the step of communicating comprises one of replying to a sending device of the message thread, replying to the sending device and all recipient devices of the message thread and forwarding the message thread to at least one device.

10. The method of claim 6 wherein the modified message threads comprise at least one attachment, the method further comprising optionally selecting an attachment for inclusion in the modified message thread.

11. A non-transitory computer readable medium comprising a memory having computer readable code embodied therein, for execution by a processor for configuring a communication device to communicate message threads over a network, the computer program product comprising instructions and data for configuring a processor of the mobile device to:

receive a message thread at a first device, the message thread comprising a plurality of sub-messages, each of the plurality of sub-messages being delineated from one another within the message thread;

receive input to compose a new sub-message associated with the message thread, the new sub-message indicating a first and at least a second sub-message recipients;

at a selection interface,

create a first modified message thread by selecting a first subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom; and

create at least a second modified message thread by selecting a second subset of the plurality of sub-messages for one of inclusion therein and exclusion therefrom, ones of the sub-messages comprising the selected first and second subsets being delineated by a respective sub-message header, the sub-message header determinable by parsing text of the message thread, the first and at least a second modified message threads comprising the new sub-message; and

initiate communication of the new sub-message, the first modified message thread communicated to the first sub-message recipient, and the at least a second modified message thread communicated to the at least a second sub-message recipient.
