I have the AT&T Cingular. One Iphone has the unlimited everything 24/7 for $30 a month. When AT&T dropped that plan we were grandfathered in to always have it at that price until we drop it. I let my niece have that unlimited on her phone as she is in school and uses wireless for everything. She's on our plan. My Iphone plan is $25 a month for a limited amount of wireless time. I have never gone over so it must be a lot for $25. I'm thinking of dropping it to the $15 a month charge. At home or in a wireless area the phone won't use the AT&T wireless, it will use the available wireless. We have 3 smart phones on one plan and I don't know the actual bill amount. I'd have to look it up. DH pays all the household bills and hasn't complained about the phone bill at all so he feels it's reasonable or I'd know about it. LOL
