Shooter's right, it is on the website when you order your phone, in fact, when you place your order, when you hit submit, a window pops up and also states that the iphone requires a $30 data plan. If you didn't read it then that's not our problem. Also, we do NOT have records to online chats or previous calls you've made to customer service, yes they are recorded however they are all stored in the corporate offices, not the call centers, so demanding it from the rep or supervisor you spoke to isn't going to help, we don't have it!!
The data plan requirement became effective in November of 2009, and AT&T was one the last carriers to require it. It is required with almost all smartphones, including Iphones, blackerrys, palm and other smartphones. It is there so you don't end up being charged for high data charges on your bill, because then no doubt you would call and bitch to the rep about that to.
Learn to read the fine print and ask direct questions, it will save you a lot of hassle. Don't blame the reps when you fuck up, grow some balls and deal with it.
