------------from nokia FAQ site.
41. After updating software with Nokia Software Updater, PC Suite synchronization doesn't seem to work. My phone shows the error message "System error" when I try to synchronize. How can I make synchronization work again?
Restoring the factory settings for your device may help.
Type "*#7370#" on your phone's keypad.
After typing this, you will be asked for a security/lock code. Please use the security code supplied with your mobile phone sales package (the default code is 12345), or if you have changed the security code, use your personal code.
Please note that if you restore factory settings, you may have to reset some phone preferences.
Note: If the code does not work, please see your phone's user guide for information on restoring factory settings.
