[Hero CDMA Android Development] chuckhriczko:
You need help uninstalling the apps? Maybe I will make a post of this but at the very least there are two places the apps are located on the phone. The apps you install from the market are in /data/app and /data/app-private. Obviously you can uninstall these from the settings app so thats not too important. What you want is in /system/app I believe. First you must mount the system as read and write. Then you can cd into that directory and then issue the dir (ls in Linux) command. This will list all the files. There are a lot of these. Just look for a filename that looks right an use the rm command to delete the application. There is a little more to it than that so let me elaborate.

Android applications are compressed files. When the app is run it decompresses the file into a temporary directory. Now as Android began evolving Google decided to seperate the app and the compressed data. This is referred to as odexing the application and while it takes more space on the phone it will speed up the application. You will notice for just about every application in this directory is an apk file and an odex file. So say you want to remove the Nascar app (probably the most hated app, sorry Nascar fans). I forget the exact filename as I removed it but it is something to the effect of Sprint_Nscar.apk and Sprint_Nscar.odex. Just issue the rm command on these files and they will be removed. You will notice they are no longer in the app drawer either. I noticed when doing this it did not show any saved space until after I restarted the phone. Don't know why this was.

One more note. Be extremely careful when doing this. If you havent done so, flash the recovery image. Then do a nandroid backup. If you remove the wrong file you can just restore the backup. And if you don't know what a file does, DO NOT TOUCH IT! You can seriously screw up the system by removing the wrong file. And without further ado, an example of the commands you should run.

At the windows command prompt (or Linux terminal):

adb shell
* daemon not running. starting it now *
* daemon started successfully *
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cd /system/app
# ls

This listing essentially removes the stocks application. Useless to me so I removed it. Simple as that. Any questions just ask.
