In any case, NM 0.7.2 and recent NM 0.8 snapshots should detect those address and substitute known-good servers for them (4.2.2.1 and 4.2.2.2). Not optimal, but at least you can get online. I see this occasionally with T-Mobile US and my Huawei stick, but I've never seen it with Option devices for example.

NetworkManager and domain names
I use NetworkManager with three's mobile broadband. I have just found out that it is not able to obtain a domain name with dhcpcd. Any ideas how I can force NetworkManager into getting a domain name from three's DHCP servers? Thanks for any advice given!
