Just to chime in; I think 2006 is broken in this way as well.

I can assign a static IP address to the device and attach to a WAP fine. I can get an address off ppp0 when connecting to EDGE/GPRS via Bluetooth to a Nokia N90 and using T-Mobile data service, but if I connect to any WAP and use dhcp I do not get an address and the dhcp client assigns the link-local address to $interface.

It seems really like a stupid bug to have, since a lot of people with the 770 will presumably be relying on dhcp to configure the device when they're at a hotspot, but whatever.

Short of waiting for an update, does anyone have any solutions? I haven't attempted to force dhclient to run, I am not entirely certain how GNU/Linux does dhcp these days.
