I tried to install a .p12 files on my Nokia 6120: I copy the files to Documents folder in the phone, I install .p12 file step by step from"Installing_Certificates_to_S60_3rd_Edition_Devices_v1_1_en.pdf".
but when I finished install,I can't find my personal certificate,and security model error;have .p12 file require special format? or another wrong?

best regard
