Without it your phone will not be able to functioning as it should be. Data such as IMEI number, menu function, etc are kept mostly in the Eeprom IC, but for security purposes could be copies at flash too and in addition it's necesary to calculate a checksum code if this information change.

Phone damage generated from incorrect data such as phonelock, security code, Nokia contact service, wrong software and wrong card messages, upgrade software data (by example convert from 3310 to 3315 with logo editing menu and other options, 6210 to 6250 or 8210 to 8250), IMEI number changed, etc would be able to be fixed by using data cable and appropriate software.

People use Eeprom Programmer hardware to access Eeprom IC data before. Disadvantages from this method is that there much more risk that you break your phone, because is needed to pull your Eeprom IC out from phone for programming. By taking the Eeprom IC out from phone, data such as IMEI number will be changed automatically to indicate that phone has been serviced.

With data cable, all disadvantages are eliminated. Access to Eeprom IC data could be done without opening the phone's housing or changing the IMEI number. Just like you charge your phone, you plug data cable in the same way.
