But other stats from T-Mobile's Q1 2013 results aren't quite so rosy.
On April 12, T-Mobile began selling the Apple iPhone 5. Four weeks later, the Deutsche Telekom subsidiary has already unloaded half a million iPhone 5 handsets. That's the banner news from T-Mobile's first-quarter results, which were made public earlier today.
"Our first quarter operating metrics and financial results are showing positive impact from the changes we began making in the fourth quarter," T-Mobile exec John Legere said in a statement. "We ended the quarter with strong operational momentum."
