AT&T: Keep grandfathered unlimited data on iPad 2, $100 off original iPadt

Worried about your unlimited AT&T iPad data if you upgrade to iPad 2, or maybe you just want to save $100 on an original iPad? Well, good news on both fronts!

First up, AT&T has confirmed to Engadget that, if you have an original iPad with a grandfathered unlimited 3G data plan, you'll be able to keep it if you upgrade to iPad 2. (We're guessing most people would have just swapped microSIMs and hoped for the best but it's good to hear it won't be a problem.) New users, of course, will only be able to get the 250MB or 2GB capped plans.

Second, if you don't have an iPad yet and price is the reason why, AT&T is also matching Apple's recent discount, shaving $100 off the cost of an original iPad 3G. That means starting price is $529 and they'll toss in a free month of data. (If you want a Wi-Fi model for $499, check Apple.)
