After studying the msgs, finally got the Symbol card working, smiling all the way while surfing the internet, it is fast, and much faster than my the other unit of Sigmarion III.
Input of SSID in the c860 is the key to make the Symbol cf card running (but at the same timeI turned off the autoconnection)
Somehow, I still failed to install the ipk files (qpe-filemanager, zeditor) which are needed to edit the conf files. For some reason, during installing the ipk file, the installer will pop up an error msg "The filename of this package includes character this application can't handle. Please change the filename and retry install". Really need help on this.
Using the Konsole is tough for me which need some times to catch up.
Thank you very much.
