The shipping plans suggest that two new iPhone models could be launched as soon as next month, pointing to a strategy shift as Apple attempts to regain its momentum in the smartphone market, the Journal noted. The company's suppliers in Asia started mass-producing components in June for both a standard iPhone featuring a metal casing and a lower-cost version, people who work at those companies told the newspaper. An Apple spokeswoman declined to comment, the Journal said. 7. -- The Justice Department is investigating whether JPMorgan Chase ( JPM) manipulated U.S. energy markets, the Journal reported, citing people familiar with the case. The bank last month agreed, without admitting wrongdoing, to pay $410 million to settle allegations raised by the Federal Energy Regulatory Commission that it manipulated markets in California and the Midwest. The DOJ decided to examine JPMorgan's energy practices in recent weeks as that settlement was being wrapped up, according to the people familiar with the probe, the Journal reported. The people cautioned the investigation is still in its early stages and the outcome uncertain.
