Sprint, the nation’s third-largest cellular carrier, reported iPhone sales of 1.5 million iPhone units in the previous quarter. Still, that wasn’t enough for the company to make money. From April through June, Sprint lost $1.37 billion, or $0.46 per share. In the same quarter of 2011, the loss was $847 million, or $0.26 cents per share.

In the second quarter, the company reported sales of $7.3 billion. Of the new iPhone sales, 40 percent were from new postpaid subscribers. In total, Sprint activated a net total of 442,000 postpaid subscribers.

Last quarter, Sprint reported iPhone activations of 1.8 million units.

Earlier, Apple, AT&T and Verizon Wireless announced their own previous quarter results.
