They also quietly announced at the same time the real news — that the $30 Unlimited Data plan on the iPad 3G will be axed in lieu of the same data plan. Yes, this would be the same "revolutionary data plan" that Steve Jobs was so proud of during the iPad unveiling — it lasted exactly 1 month after the 3G model was delayed to May 7th. People feeling vibes of previous Apple iDevice releases are not alone. Existing accounts will be allowed to grandfather in, although Apple has removed the ability to purchase the iPad from the online store at this time, and AT&T has a history of changing their plans without warning. Finally, there is no word on what happens if you ever let your Unlimited plan lapse for a month at this time.
