Why would you post the same thing in two different forums?

For the updates as well you can do the same except you don't have to remove anything.

So you download these files in /home/user/MyDocs/
gingerbread_update1.tar.bz2
gingerbread_update2.tar.bz2
gingerbread_superuser.tar.bz2
LatinIME.apk
gps.nokia.so

Follow these steps first to uncompress the bz2 files:
# root
# bzip2 -d gingerbread_update1.tar.bz2
# bzip2 -d gingerbread_update2.tar.bz2
# bzip2 -d gingerbread_superuser.tar.bz2

Now mount /and change directory to /and:

# mount /dev/mmcblk1p2 /and
# cd /and
# tar xvf /home/user/MyDocs/gingerbread_update1.tar
# tar xvf /home/user/MyDocs/gingerbread_update2.tar
# tar xvf /home/user/MyDocs/gingerbread_superuser.tar

You will notice the files getting copied after every tar command above that you execute.

The last ones are not tar files so u can just move them to the respective location:

# mv /home/user/MyDocs/LatinIME.apk /and/system/app
# mv /home/user/MyDocs/gps.nokia.so /and/system/lib/hw/

Finally change directory and unmount:

# cd
# umount /and
