4. The wireless communicator of claim 2 wherein the one or more pre-designated phone number comprise phone numbers of parents of a child who uses the wireless communicator.

5. The wireless communicator of claim 2 wherein said controller is further operable to allow outgoing phone calls when said pre-designated cumulative power limit is exceeded, if the wireless communicator is used in a low radiation listening mode.

6. The wireless communicator of claim 5 further comprising a hands-free speaker that can be coupled with said controller, and wherein the low radiation listening mode comprises listening to phone calls through said hands-free speaker.

7. The wireless communicator of claim 5 further comprising a low radiation headset that can be coupled with said controller, and wherein the low radiation listening mode comprises listening to phone calls through said air-tube earphones.

8. The wireless communicator of claim 7 wherein said low radiation headset comprises air-tube earphones.

9. The wireless communicator of claim 7 wherein said low radiation headset comprises wired earphones.

10. The wireless communicator of claim 7 wherein said low radiation headset comprises a Bluetooth headset.

11. The wireless communicator of claim 1 further comprising a mechanism for activating and deactivating said controller to respectively control and to not control operation of said modem based on data provided by said radiation monitor.

12. The wireless communicator of claim 11 wherein said mechanism activates said controller to control operation of said modem based on data provided by said radiation monitor, upon user entry of a password.

13. The wireless communicator of claim 11 further comprising a jacket device into which the wireless communicator may be inserted, wherein said controller is automatically activated to control operation of said modem based on data provided by said radiation monitor, when the wireless communicator is inserted into said jacket device.

14. The wireless communicator of claim 11 wherein the wireless communicator may be locked in said jacket device so that it cannot be removed therefrom by a child.

15. The wireless communicator of claim 1 wherein pre-designated daily cumulative power limit is calibrated according to a user'"'"'s gender, age and weight.

16. The wireless communicator of claim 1 wherein the pre-designated daily cumulative power limit is calibrated according to a frequency of transmission of said modem.

17. The wireless communicator of claim 1 further comprising at least one audio component, and wherein the pre-designated daily cumulative power limit is calibrated according to the nature of said at least one audio component.

18. The wireless communicator of claim 17 wherein said at least one audio component comprises at least one member of the group consisting of a speaker, an earpiece, a microphone, a hands-free headset, a car kit and air-tube earphones.

19. The wireless communicator of claim 1 further comprising a jacket device into which the wireless communicator may be inserted, and wherein the pre-designated daily cumulative power limit is calibrated according to a SAR profile of the jacket device.

20. A wireless communicator, comprising:

a modem operable to transmit and receive voice communication phone calls;

a hands-free speaker; and

a controller coupled with said modem and with said hands-free speaker, the controller being operable to direct a phone call through said hands-free speaker between the time that the phone call is made and the time when a person answers the phone call.

21. A wireless communicator, comprising:

a modem operable to transmit and receive voice communication phone calls; and

a controller coupled with said modem comprising a monitor operable to monitor an ongoing call, the controller being operable to restrict operation of said modem, based on data provided by the monitor, when the ongoing phone call exceeds a pre-designated length of time.

22. A wireless communicator, comprising:

a modem operable to transmit and receive voice communication phone calls; and

a controller coupled with said modem comprising a monitor operable to monitor reception strength of voice communication, the controller being operable to restrict operation of said modem, based on data provided by the monitor, when the reception strength is below a pre-designated threshold.

23. A wireless communicator, comprising:

a modem operable to transmit and receive voice communication phone calls;

an accelerometer to measure an angle of orientation; and

a controller coupled with said modem and with said accelerometer, the controller being operable to restrict operation of said modem when said accelerometer indicates a substantially stationary angle of orientation longer than a pre-designated length of time.

24. A method for limiting radiation transmitted by a wireless communicator, comprising:

monitoring power output of a wireless communicator, the wireless communicator being used to send and receive voice communication phone calls;

determining if the cumulative power output exceeds a pre-designated daily cumulative power limit; and

restricting operation of the wireless communicator when said determining is affirmative, comprising limiting usage of the wireless communicator when the wireless communicator is not being used in a low radiation listening mode.

25. The method of claim 24 wherein the low radiation listening mode comprises using the wireless communicator with a hands-free speaker.

26. The method of claim 24 wherein the low radiation listening mode comprises using the wireless communicator with a low radiation headset.
