You could also use ADB if you want to back the stuff up while you're removing it. Use pull to copy to your computer, run the shell, mount your system folder, and use the aforementioned rm to remove the .apks.
What I did to get rid of that annoying bloatware was to open up command prompt.
Then type in the following commands
su mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system cd /system/app ls - that is a LS not IS
Once you type in ls you will see all of the apps that are on your phone. Find the ones that you want and type in the following.. I will use Blockbuster as an example.
mv Blockbuster.apk Blockbuster.bak
This command will essentially make it so the phone cant read the application, and therefore will not start it up or anything. If you ever needed to get it back in the future just switch the above code from .bak back to .apk.
Once you have deleted all of the apps you no longer want just run
I'm a linux user so I always love trimming down the fat in my desktops/fileserver, however I would advise against this. I went to wipe my phone to start fresh again and nearly bricked it just trying to get the bloatware back on so that it would wipe fine. It was a mess and I barely made it back.
What I would suggest however, is getting Autostarts and working your way through every section and disabling some of the programs. You can get it to not boot up CityID for example, meaning the app is still on the phone safely, but it won't even start the app. Peace of mind knowing the app is still safe for wiping the phone, yet won't boot into RAM and use CPU.
