i should be careful posting this, since i have AT&T cellphones...
according to the AT&T terms of service agreement here:
http://home.bellsouth.net/csbellsout...tt.htm&leg=tos
para 5 5.1, "AT&T may immediately terminate or suspend all or a portion of your Service, any Member ID, electronic mail address, IP address, Universal Resource Locator or domain name used by you, without notice, for conduct that AT&T believes ....(c) tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries.
i am sure they are somehow covering their butts on something, but doesn't this sound a bit...censorship-y to you?
