T-Mobile USA has revealed that the recently launched Samsung Galaxy S III smartphone has now become their bestselling device of all times.

This phone went on sale on their network around four months ago.

T-Mobile USA of course does not sell the Apple iPhone officially.

Samsung has already sold more than 20 million units of the S III smartphone globally.

We imagine that they are already nearing another major milestone looking at how successful this model has been for them.
