T-Mobile is Readying UnCarrier 4.0, Any Predictions?

Ready for part 4 of T-Mobile’s UnCarrier movement? We have already seen them attempt to rid the world of contracts, remove subsidies from phone bills, introduce innovative new upgrade plans, hand out 200MB of free data to all tablet owners, and give away free unlimited data across the globe in over 100 countries. It’s been quite the year for T-Mo, to say the least. According to a recent Tweet from T-Mobile’s CEO John Legere, there is more to come in early 2014. 

In his Tweet, all he mentioned was that it is “time to eliminate another customer pain point,” and that CEO of AT&T, Randall Stephenson, should have a happy New Year. Nice dig.

So what could he have in mind? I feel like T-Mobile has already eliminated so many paint points. Any guesses?
