@mrman2787, I think there are some posts here that describe how you can call AT&T and have them manually change your cell phone type to a dumb phone and avoid data charges.
Being jailbroken or not won't change anything as far as how AT&T detects what kind of phone you have, so talking to customer service and having them make this change manually is probably the only way.
I believe that you need to use a prepaid account.
The network will auto detect it's an iPhone & a data plan will be added to your account. It has nothing to do with jailbreaking. You have no choice.
Not possible. No way. Period.
Don't believe me, do your part & read the terms & conditions. You don't have a chance.
Nope, not if you have a "data opt - out" on your account.
OP, what phone do you currently have and do you have internet on it?
Go to your account via www.att.com and check to see if you have "data opt out" under your line if you do not have data.
That doesnt make a difference.
They do scans and the minute they detect an iphone on a post paid account without a data plan they will add it automaticly.
They have been doing that since last summer.
You can use a prepaid AT&T gophone sim in order not to have a data plan. If you're on a monthly plan they will add it for you.
Try it and see how long you last. Some get away with it for months and others weeks.
