Unlimited data for AT&T iPhone still available

Good news for all the customers that had the unlimited plan while they had the 3Gs and now have Iphone 4 but no unlimited plan. There is a loophole where all the customers that had the unlimited plan can switch back to their unlimited plan on their Iphone 4 or any smart phone(though this is not confirmed). This is not available online and you have to call At&t to ask them to switch back
