    I'm rooted. Saw a brief video on how to remove unwanted factory apps. I'm so damn retarded that I failed even after watching the video! The video showed this being done on a Tmobile G1. Maybe it's different on the Droid?

    I opened up Terminal Emulator and here is how my session went:

    $ su
    # mount -o rw.remount /system (enter)
    Usage: mount [-r] [-w] [-o options] [-t type] device directory
    # rm -r /system/app/Twitter.apk
    rm failed for /system/app/Twitter.apk, read-only file system

    I don't know anything about Linux, but I do know enough about windows that it appears the first line of the above statement is trying to make the file re-writeable (hence the rw) but it's failing. That's why line 2 can't remove (rm?) the app.

    So, can anyone correct me in my line 1 above? Thanks! I know, I need to pick up a linux book.

    You are rooted, at least thats in your favor. Are you running a custom ROM, or are you just rooted? The reason I am asking is most developers code in a way to remove bloat from their roms. Secondly, you really dont want to remove bloat, because that will remove the app from your phone completely with no hope of replacing it if you need it. Instead, change the extension from .apk to .bak . The easiest way is using root explorer from the market.

    I'm just rooted, no custom ROMs or Kernels. And believe me, I want to remove some factory apps. I will kill myself using a very painful method of suicide if I ever become a fan of Twitter. I want that program completely gone!

    I figured out that in my line 1, I needed to put a coma instead of a period here:

    # mount -o rw,remount /system

    But I still get the same error. Just wanna know what I'm doing wrong.

    I have scripts set up on my phone so I don't have to use that whole command line, but entering adb remount will set your phone to rw and is much easier than the command line above. Let me know if you would like the link to the script package.

    Just use Astro and delete the apps you don't want from /system/app

    Don't bother with command lines.

    I was thinking that. I'm all about doing things the easy way.

    Astro won't allow me to delete that apk. It says error when I try to delete it or change it's extension. I think it's because it's a read only file and the attribute needs to be changed first. And I haven't tried root explorer yet as I don't wanna buy it since what I'm trying to accomplish can be done for free.

    And I know adb will allow me to do it. But I'm trying to learn, not just do. I can't believe no one has been able to tell me what's wrong with my command line!

    Thanks for all the suggestions though.

    Seems like you are having issues mounting the system partition, try this:

    Boot to recovery, mount system partition through recovery, connect phone to PC

    then run the rm command thru Adb

    Something like:

    rm system/app/Twitter.apk
