Bruce Kushnick does on an expose on AT&T’s iphone deal. Kushnick is a telco expert who I’ve linked to before. He disapproves of the business practices of the telcos. He’s strident but usually has his facts right.

But for the record, I use the significantly cheaper prepaid Virgin Mobile service ($7/month) with no contract. (Read my comment below).
