no point is getting iphone without data any way
It's funny, AT&T is the only GSM provider that will mandate a data plan on a customer owned and maintained device (as far as I know).
I work for Glentel and in the Atlantic region (where I work) we sell Bell, Rogers and Virgin (owned by Bell in Canada). People bring in unlocked/outright iPhones all the time and opt for the $20/mo talk and text plan. None of our providers enforce it unless the phone was subsidized and the user is currently on contract.
