come posso sbloccare il mio telefono se ho dimenticato il codice di sicurezza
I guess (thanks to Google translate) the question is how to unlock the phone if the security code has been forgotten. Hopefully this support article will help: http://www.f-secure.com/en/web/home_global/support/article/kba/2791. If you forgot your Mobile Security lock code, please open a support request via http://www.f-secure.com/en/web/home_global/support/contact/request
No idea what your problem is...
Please repeat in English.
