In a very odd move, less than a month after the launch of the iPad 3G, AT&T are changing the iPad data plans and getting rid of the unlimited data plan. As mentioned in a previous article, AT&T are modifying their data plans and going forward will only support a 200MB for $15/mo and 2GB for $25/mo plans.
Since iPad users are not under contract, AT&T has the right to change the plans as often as they like. But if you are currently subscribed to one of the old plans, you can keep using that plan. Going forward though, instead of the 250MB and unlimited data plans, customers will have the option to purchase 2GB of data for $25/month. And instead of $15 for 250MB, iPad users will only get 200MB for $15/month.
I'm found it hard use up the 250MB plan in the first month of use. I only used around 150MB on my iPad 3G, so I don't think I'll switch to the unlimited plan. But I'm happy to keep getting and extra 50 MB for my $15 per month.
