“Small percentage” of T-Mobile customers to be offered unlimited LTE for the rest of the year, no extra charge

It is not an April Fool’s joke. The only thing we do not know for sure is how T-Mobile is choosing which lucky customers will be offered the deal. T-Mobile customers selected for the promotion will get a text message with the offer.
Another feature that is removed is Data Stash. While that arguably does not matter with this promotion, who knows what T-Mobile’s rate plan structure will look like at the end of the year.
Are you a T-Mobile customer? Were you offered this promotion? Did you take it?
