a holder; and
a cutting insert attached to an outer part of the holder at a front end according to claim 1, wherein
at least a part of the plurality of divided cutting edges protrudes outwards from the outer part of the holder at the front end.
9. The cutting tool according to claim 8 wherein
the cutting insert attached to the holder, the plurality of divided cutting edges thereof having a positive axial rake angle.
10. A method of cutting a workpiece by use of the cutting tool according to claim 8, comprising:
rotating the cutting tool;
bringing at least a part of the plurality of divided cutting edges of the rotating cutting tool into contact with a surface of the workpiece; and
separating the workpiece from the cutting tool.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1-23. (canceled)
24. A wireless communications device comprising:

determine at least one filtered received text message based upon at least one audio message filter parameter,
switch to a hands-free audio message mode based upon determining establishment of the headset connection, and
when in the hands-free audio message mode, output at least one audio message comprising speech generated from the at least one filtered received text message via said headset output.
25. The wireless communications device of claim 24 wherein the at least one audio message filter parameter is based upon a sender’s identity.
26. The wireless communications device of claim 24 wherein the at least one audio message filter parameter comprises at least one of a sender’s name, a sender’s address, a keyword, a message priority, a time or date, and a copied person’s identity.
27. The wireless communications device of claim 24 wherein said headset output comprises a wireless headset output.
28. The wireless communications device of claim 24 wherein said headset output comprises a wired headset output.
29. The wireless communications device of claim 24 further comprising a user interface device coupled to said controller; and wherein said controller is further configured to switch to the hands-free audio message mode based upon an audio message mode command provided via said user interface device.
30. The wireless communications device of claim 29 wherein said user interface device comprises a keypad.
31. The wireless communications device of claim 24 further comprising a text-to-speech module configured to convert the at least one filtered received text message to the at least one audio message.
32. The wireless communications device of claim 24 further comprising a display coupled to said controller for displaying the at least one filtered received text message.
33. A wireless communications device comprising:
a headset circuit configured to establish a headset connection;
a wireless transceiver;
a controller coupled to said wireless transceiver and said headset circuit and configured to
determine at least one filtered received text message based upon a sender’s identity,
switch to a hands-free audio message mode based upon determining establishment of the headset connection, and
when in the hands-free audio message mode, output at least one audio message comprising speech generated from the at least one filtered received text message via said headset output; and
a display coupled to said controller for displaying the at least one filtered received text message.
34. The wireless communications device of claim 33 wherein said headset output comprises a wireless headset output.
35. The wireless communications device of claim 33 wherein said headset output comprises a wired headset output.
36. The wireless communications device of claim 33 further comprising a user interface device coupled to said controller; and wherein said controller is further configured to switch to the hands-free audio message mode based upon an audio message mode command provided via said user interface device.
37. The wireless communications device of claim 33 further comprising a text-to-speech module configured to convert the at least one filtered received text message to the at least one audio message.
