Late last night – or at least, very early hours of the morning for me – CEO John Legere hinted at the arrival of the next phase of the Uncarrier movement. In his tweet, as you can see above, he announces that Tmo is set to release customers from another “pain point”. Exactly what that is, I don’t know, and I can only guess.

So far, “pain points” already struck off the list include having to wait two years before upgrading, international roaming charges, having the cost of a phone hidden away in the cost of your monthly plan, and – more recently – tablets.

What could this phase 4.0 be then? Will it be unlimited data on any device with no restrictions of any kind? Will it be a cable/home internet partnership with Dish Network? Rumors surrounding the two companies have appeared on and off for a while over the past few months. We’ve even had emails from readers saying they’re getting a Dish Network automated recording when going through various options on a customer service call to T-Mobile.

All we can do at this point is hope and speculate. If I hear anything more concrete, I’ll be sure to update the site.
