Not sure where, but I thought I saw a reference to people who lost their grandfathered unlimited data plan when upgrading to the iPhone 4S. I know that if add tethering, you lost your plan. This is the first I've heard of upgrading causing a change in plan.
Anyone have unlimited data? Have you seen anything to indicate you will lose your unlimited plan post-iphone 4S upgrade?
