Aside from the original iPad data plan which I believe was unlimited - is there currently an unlimited data plan for the iPad? In other words - if I go buy an iPad today, is there a way to get unlimited data? I have AT&T as my iPhone provide - and I have an unlimited iPhone plan because I purchased the original iPhone many years ago. I also have AT&T Uverse as my home television provider (U450 plan.) If I was to go purchase a new iPad today, is there a way for me to get unlimited data? Thank you.
