Hi,

I was trying to install an app called Total Patrol (which gives me reminders about missed SMS/calls) but I keep getting certificate errors and to contact the vendor.

I saw on other threads mention that you need to go to "App Mgr", then set Software installation to All and Online cert check to Off - however, even when I do this, my E52 still won't let me install the unsigned application.

Is this an issue with E52s or is there another way to install such apps?

Thanks in advance!

You'll need to get the app signed first.

oooh, what does this app do?

This organisation certifies Symbian apps written by developers. It's a safety precaution for users. There are several ways to get Symbian apps signed.
