3G USB Dongle usage

[RJV]

Thanks for your patience in response to my quite simple queries.

About me, I have worked on Mac OS X about 7-8 years back with Objective C
and am familiar with the Unix, BSD and Ubuntu environments but again from
some time back. What I wanted to know was the interface between Sugar and
GNOME. Your "GNOME also provides a middle level that Sugar uses. " helps in
that direction.

Will switch to XO after this email and mail the log messages maybe
tomorrow. Have to get some sleep, too.

Regards,

Jv
