Nah, Softbank Mobile's launch of the iPhone isn't entirely to thank for the carrier notching record operating profits this quarter, but it certainly didn't hurt matters. Noting that Apple's darling "pulled in more mobile subscribers," the company reported an operating profit of ¥180 billion ($1.85 billion), though net profit did slide 11.5% to ¥41.1 billion ($422.2 million). In fact, Softbank president Masayoshi Son proclaimed that he used an iPhone every day, telling the press that it was "useful, and the more that [he] uses it, the better [he] understands its strong points." Of note, the operator's retention of mobile phone customers "has also improved with the iPhone," and while income from voice calls continues to drop, earnings from data services were on the up and up. Data, kids -- that's the future!
