Information system with detachable information module

1. A communication module for use with a mobile communication device configured to wirelessly communicate through a wireless cellular network, the communication module comprising:

a communication subsystem configured to communicate through a first communication network other than the wireless cellular network;

a communication port configured to

(i) establish, with the mobile communication device, a direct non-network-based short-range wireless link that is based on neither the first communication network nor the wireless cellular network, and

(ii) receive, from the mobile communication device through the short-range wireless link, contact information that is stored in the mobile communication device, wherein the contact information relates to a contact of that the mobile communication device is configured to communicate with over the wireless cellular network;

a memory configured to store the contact information; and

a processing subsystem configured to use the stored contact information to initiate a communication, through the first communication network, between the communication module and the contact.

2. The communication module of claim 1 wherein the communication module is configured to receive and store the contact information automatically when the short-range wireless link to the mobile communication device is established.

3. The communication module of claim 1 wherein the communication module is configured to receive and store the contact information in response to a user input.

4. The communication module of claim 1 wherein the communication module is configured to

previous to receiving the contact information, store information regarding the contact in the memory; and

after receiving the contact information, use the received contact information to update the previously-stored information that is in the memory.

5. The communication module of claim 1 wherein the communication module is configured to

receive, from a user interface, information related to the contact; and

send the received information through the short-range link to the mobile communication device.

6. The communication module of claim 1 wherein the communication module comprises a telephone, the first communication network is a wired telephone network, the contact information includes a phone number of the contact of the mobile communication device, the communication is a phone call, and the communication module initiating the communication comprises the communication module using the phone number to place the phone call.

7. The communication module of claim 1 wherein the contact information includes a contact telephone number.

8. The communication module of claim 1 wherein the communication module is configured to restrict access to data stored in the communication module, and the communication port is configured to receive an identification number of the mobile communication device from the cellular mobile communication device through the short-range wireless link from the mobile communication device, which causes the communication module to enable access to the data.

9. A method performed by a communication module that is configured to communicate through a first communication network, the method comprising:

(i) establishing a direct non-network-based short-range wireless link with a mobile communication device that is configured to wirelessly communicate through a wireless cellular network;

(ii) receiving, from the mobile communication device through the short-range wireless link, contact information that is stored in the mobile communication device, wherein the contact information relates to a contact that the mobile communication device is configured to communicate with over the wireless cellular network;

(iii) storing the contact information in a memory; and

(iv) using the stored contact information to initiate a communication with the contact through the first communication network;

wherein the communication module performs steps (i)-(iv); and

wherein the short-range wireless link is based on neither the first communication network nor the wireless cellular network.

10. The method of claim 9 wherein the receiving and the storing are performed automatically by the communication module when the short-range wireless link to the mobile communication device is established.

11. The method of claim 9 wherein the receiving and the storing are performed in response to a user input.

12. The method of claim 9 further comprising:

previous to receiving the contact information, store information regarding the contact in the memory; and

after receiving the contact information, using the received contact information to update the previously-stored information that is in the memory.

13. The method of claim 9 further comprising:

receiving, from a user interface, information related to a contact; and

sending the received information to the mobile communication device through the short-range link.

14. The method of claim 9 wherein the communication module comprises a telephone, the first communication network is a wired telephone network, the contact information includes a telephone number of the contact of the mobile communication device, the communication is a phone call, and the communication module initiating the communication comprises the communication module using the phone number to place the phone call.

15. The method of claim 9 wherein the contact information includes a contact telephone number.

16. The method of claim 9 further comprising:

the communication module restricting access to data stored in the communication module;

the communication module receiving an identification number of the mobile communication device from the mobile communication device through the short-range wireless connection; and

based on the identification number, the communication module enabling access to the data.

17. The method of claim 9 further comprising:

the communication module restricting use of a particular function of the communication module;

the communication module receiving an identification number of the mobile communication device from the mobile communication device through the short-range wireless connection; and

based on the identification number, the communication module enabling use of the particular function.

18. The method of claim 9 wherein the receiving of the contact information by the communication module is automatically invoked when the mobile communication device is mounted on the communication module.

19. The method of claim 9 wherein the short-range communication link is through infrared transmission.
