Unable to import S/MIME certificate and key into my iPhone (iOS7) I tried to generate a S/MIME certificate from comodo.com. On my Mac it perfectly works. But I am unable to use it on iOS 7. This is what I did:


generate certificate on Mac
export certificate and private key in p12 format from keychain
sent the p12 and the Comodo cert (COMODO Client Authentication and Secure Email CA.cer) via email to iphone
import both certificates
enable S/MIME in email client on iPhone


When I look into my Profiles (General > Profiles) I see the comodo certificate as TRUSTED (1) as well as my private cert (2) . But when I look into the S/MIME settings from the email account on iPhone it is NOT TRUSTED (3).





My emails got not signed / encrypted then.

What am I doing wrong? I am lost.
Surprisingly I had a look into my certificate in the mail accounts section. It was untrusted. I then got into the section of profiles and had a look into the imported profile. It was trusted.

Then I went back to the certificate in the mail account section and it was trusted!

This seems all quite buggy, Apple.
