Following its bittersweet Q3, the latest financial report from Sprint this quarter offers up another mixed bag of news. Net operating losses totalled $438 million, more than the $139 million posted in the same quarter last year. It made a $1.3 billion net loss, dwarfing the Q3's $301 million losses. Operating revenue increases were, however, the largest in the last five years. Net subscribers now total 55 million, with 33 million postpaid, 14.8 million prepaid and around 7.2 million arriving from wholesale. Sprint hoped to see the iPhone draw customers into its network, putting it toe-to-toe with the bigger carriers, and it largely did, with 40 percent of iPhone sales landing directly in the hands of new customers. Last year also saw the tentative launch of Sprint's LTE network.
