Sprint’s Q1 2013 financial results came out this morning, and the news wasn’t great overall. Losses continue to accumulate, and total smartphone sales aren’t faring very well, either, with just 5 million units sold in total. The iPhone, after achieving a record high of 2.2 million handsets sold on Sprint’s network last quarter, dropped back down to 1.5 million, the same number Sprint saw in the three quarters preceding Q4 2012.
