Has anyone who purchased an iPad prior to June 7th but got it after that date actually been able to get the unlimited plan? The iPad page on the web Apple Store says that you can, but when I called them and asked how, I was referred to Tech Support, where I was brushed off with the comment "Apple just sells the units, AT&T sells the plans". The tech rep called his supervisor who said I would have to provide AT&T with "proof of purchase" but that it would be "up to them" to honor the deal or not. If anyone who got their iPad after June 7 has actually been able to sign up for unlimited data, please tell me how you did it!
