I'm wondering if StartCom is a trusted CA on iOS.
I'd like to setup a mail server for a TLD, and use their free certificate. It's only about $10/year cheaper than more well known authorities, so the deciding factor is if it's trusted on my iPhone.
I know it is on OS X, Windows and many linux distributions, but would like to be certain.
You should be able to view and remove certificates or S/Mime if you go to:
Please also check out this Official Apple Guide By clicking the name in the Mail.App you should be able to revoke the certificate.

It turns out that iOS 5 and newer no longer trust certificates that are signed with the MD5 hash algorithm. This is confirmed by the official Apple support document http://support.apple.com/kb/TS4133.
The current CAcert root certificate is signed with MD5, so there is no fix for the problem until CAcert issues a new root certificate.

I think this Apple support article has the list you're looking for. It is updated as changes are made:
iOS: List of available trusted root certificates
And StartCom is on there.
