I have the mobile broadband lite.

My n800 can connect happily to my Sony Ericsson w950 and my friend's skype phone.

His n800 can connect happily to my Sony Ericsson, but _not_ his skype phone.

If I add the "at+cgatt=0" he can connect to his skype phone, but not browse. I have since determined that this is because he is not picking up the dns servers. I have set in a publicly accessible DNS server in his connection config, and he can now browse to public sites (like google) but not to three's sites
