Thank you for all the help you guys have given to me.

After I got penguinbait's tar and tried again, I still got corrupted file warning. I think I found the problem. For some reason, when I downloaded the KDE358v2.tar.bz2 from the website www.tablethacker.com, I couldn't get the whole file (whether I downloaded to WinXP Pro or directly to n800). The size of the file should be 316121 bytes, but I only got part of the file; sometimes it's 250KD, sometimes 240KB....).

I'll try to download it again.

By the way, I was unable to "apt-get -d install tar" (reinstall the tar). I just used it this way (root user) /home/user/tar jxvf /media/mmc1/Download/Kde/KDE358v2.tar.bz2

Thank you guys.

I used the menu button to select tool/download the file, it tool a long time (1 hr or 3 hrs?) to get it done. I used tar jtvf option to check the bz2 file and made sure it's ok (it took a long time to finish checking). I finally installed the bz2 file and the SUP file (about 50 min to 1 hr to finish tar-ing). My Kde v2 is running now. I have a lot to learn about this new version. First of all, I have to find out where the virtual keyboard is. On the Kde v1, the virtual keyboard is around handy. The KDE on N800 is really a masterpiece. Now I can catch up with you guys on enjoying the KDE V2.
