http://forums.appleinsider.com/showthread.php?s=&threadid=117877 AT&T is changing the data plan on Feb 13th for existing and new customers who want to tether their smart phones. 1. Data Pro=2GB for 25 dollars. 10 dollars additional charge per GB (Stays Same) 2. Data Pro + tethering = 2GB for 45 dollars will be axed. 3. 4GB data plan= The user will pay 45 dollars a month and get 4GB data per months and they will be able to use it anyway they want. They can tether or use it on their smart phones. Better than what they had before, but it still sucks. The first smartphone will be eligible for this plan is HTC inspire 4G, but you can safely assume iPhone 4 users will be eligible when apple releases iOS 4.3 on iOS devices.
