While I doubt cash rewards would be possible, simply removing the data cap would be an impressive victory.

I'm more interested in seeing that the new plans don't raise my costs for capped plan that provides the amount of bandwidth I need. If I use 2.5gb a month on my unlimited for 29.99 plan. if my wife uses 1.5gb, then the new shared everything plan raises my bill by ~20 dollars without adding any real value. I don't need unlimited talk and text.
