Go to a command prompt and type "adb shell"
You should see a # sign, that's the root terminal on your phone.
In order to remove apps, you need to remount your system folder on the phone with write permissions. To do this type "mount -o rw,remount /dev/block/mtdblock3 /system" (it won't say anything it will just go back to a # sign again)
Now type "cd /system/app" and then "ls"
That will list all the apk files, which are the applications.
You can remove them by typing "rm -r Whatever.apk" (it's case sensitive)
BE VERY CAREFUL doing this. Don't just go around deleting apps. Some may not be safe to delete as they are connected with other apps, etc. Those three I posted are safe to delete.
