When I was trying to update my KDE (n800, os2008, on mmc2 (internal 4 gb)) and following the instruction: (as a root user)
cd /
tar jxvf KDE358.tar.bz2

I got "invalid option......". My tar is BusyBox v1.6.1 (2007-09-27). When I checked the option of my default tar, I found out that it doesn't have the j option. Later on I used /usr/bin/tar (this version actually is an older version, GNU 1.5) and tried to do the same thing, but I missed typing something, so it didn't get through with installing KDE356.tar.bz2. When I corrected the typing and did /usr/bin/tar again, I got something says: use bzip2recover. I couldn't find where I could down that executable for n800.

Pleas help.
