How to cleanly delete stock apps?

[Guest Mildew]

There are some stock apps that I don't need. I want to delete them to clean up space. Apps like Opera 9 that came with the phone by default. How can I delete that cleanly? If I just delete the entire folder, would the Opera icon still be there on screen?

I think it is not possible to delete them. Files from stock apps are located in the windows folder and sometimes when I delete files from the windows folder, it just comes back automatically. That's maybe one of the reasons why they cook roms and there when they cook the rom delete those apps.
