Very good! I too think this last bit^ will be the case and may very well be the game changer they speak of. We may have seen in the past how a balance of things like "Churn rate", "ARPU", and handset introduction and customer upgrade schedules could put pressure on US carriers to maintain the status quo regarding “locked in” contacts contracts and early termination fees. Any carrier, the thinking went, that broke with this status quo would eventually gain the most from attrition provided their service satisfied the coverage needs of new customers. However, others reasoned that such a carrier would experience significantly reduced revenue until the right combination of handsets were available and enough potential customers were "out of contract" with other carriers. Perhaps because of some of the conditions you remark about earlier in your post, T-Mo has found itself in a position financially to ride out established upgrade schedules and reap the future pay-off of increased market share.
