i forgoted my pasword on 5230.how can i clean up my memory?
To format or clean up the phone memory, you can dial *#7370# in the dialler and enter the security code. The default security code is 12345. If you changed the code and can't remember it, you need to bring the device to the nearest repair facility to reset it for you.
You can visit this link for the local Nokia support and to check the nearest repair facility in your area: http://www.nokia.com/global/support/locations/
Hope this helps.
You will need to backup device using Nokia Suite as any applications / games installed upon phone memory will be deleted also. Note that any such installed upon memory card will re-install when microSD re-inserted and that although you can re-download paid for ones from Nokia Store a maximum of 10 times there is a 12 month limit on purchases.
