Announcing that it would finally begin offering Apple’s iPhone handsets on its networks back in December, T-Mobile USA CEO John Legere has provided a loose timeframe for the sale of the smartphones, which are set to become available in “three to four months.”

In an interview with Reuters at the CES expo in Las Vegas, Legere reiterated that T-Mobile USA would seek to differentiate its offering from its bigger rivals — including AT&T and Verizon — which would see the company scrap subsidies, a first for US mobile operators.

Earlier on Tuesday, Legere told attendees at the Citi Global Internet, Media and Telecommunications conference in Las Vegas that T-Mobile USA currently serves 1.9 million iPhone devices and is adding 100,000 new devices every month, even before it officially offers the Apple handsets.

At the end of last year, Rene Obermann, Deutsche Telekon’s Chairman (T-Mobile’s parent company) discussed the company’s plans, which include building on the spectrum swap with Verizon, selling off its towers to Crown Castle and the buyout of smaller operator MetroPCS — increasing its competitiveness in the US.

With the iPhone soon to go on sale, T-Mobile USA hopes it can close the gap between AT&T and Verizon, cementing its position as the third biggest US carrier.
