When the iPad first debuted, it launched with a $30 unlimited, month-by-month data over 3G courtesy of AT&T… who within months recanted the deal and switched it out with a 2GB per month subscription plan for $5 less per month.
AT&T couldn’t just bait-and-switch existing customers, though: as long as you signed up for the original unlimited plan and never cancelled, they couldn’t downgrade all existing customers to 2GB. That left a big question: when Apple finally announced the iPad 2, would AT&T figure out a way to weasel out of the grandfathered unlimited subscriptions once and for all?
Apparently not: AT&T has just confirmed that grandfathered unlimited data plans will continue to be offered on the iPad 2. So if you’ve got grandfathered unlimited, rest easy: you can upgrade to the iPad 2 safely.
