ProfiMail and the Gmail "untrusted certificate"

If you read your email on a Series 60 phone, you probably use ProfiMail, a very nice mobile email client.

However, when you configure it to access a Gmail account, you will always get the “This site uses an untrusted certificate” message. Quite annoying, since it requires 2 key presses to pass. Every single time. There’s no option for “I know, just ignore it from now on”.

The cause of the problem is that Series 60 phones, much like web browsers, have a list of trusted root certificates, and the one Gmail uses, from Equifax, isn’t in it.

How to fix it? I search around, and didn’t find a single page with instructions on how to solve this thing. But, by combining this and this, I was able to remove that annoying prompt for good.

Here’s how to do it:

• Using the phone’s browser (Opera also works), browse to http://www.ocasta.co.uk/cert.html. Click on the only link on that page.
• It should prompt you to install the certificate. Accept it.
• It should ask you what you want to trust the certificate for. Choose “Internet”.

This works on my Nokia 6630. Other phones may simply install the certificate, after which you have to go to Settings, Security, Certificate Management, and set the new Equifax certificate as “Trusted”.
