Has anybody seen these yet? From what I understand if you have the $29.99 unlimited data plan you can continue with it when your contract expires and upgrade to a new phone and want to pay the un-subsidized price of the phone which for an iPhone is an extra $400. The new data rate plans are sold in increments of 1gb and can be shared between devices and starts at $50. I am not due for an upgrade until December, and if I do I think paying $400 + the cost of the phone and $29.99 monthly for unlimited data for 24 months is much cheaper than paying $199 for a new phone and $50 for 1gb of data when I do average 2 - 3 gb monthly. Each gb of data is $10 monthly. Am I understanding the new plans??
