How to install an application signing certificate on a Motorola phone?

Question

Motorola phones do not have Verisign / Thawte root certificates for signing code. They only implement the Java UTI certificate, which requires you to sign your application for each phone model for which you want to sign the application (and this is every time you want to use a new version of the application).

I created a simple web page that points to a certificate (DER format) to check if the certificate can be installed.

On Nokia phones, it works fine. On Motorola, the phone says "unknown file format."

Is there any way to make this work? The file has the extension ".cer", right?

Thanks in advance!

The last time I had to do something like this, I’m afraid that in order to sign the application, I needed to get Motorola. However, this was due to the current problems of the Motorola mobile phone. Hope this is still possible.
