Fast questions (email, GPRS, WiFi...)

well, i did what
http://wiki.openmoko.org/wiki/GTA02_wlan
says -- adding

iface eth0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

to /etc/network/interfaces. make sure, the path to wpa_supplicant.conf  
matches yours.
to fire wkan w/ wpa up i have to do

ifup eth0

not sure, though, what's the diff between ifup eth0 and ifconfig eth0 up  
internally, but only the first yielded results.
