Research In Motion Ltd. saw its shares fall Thursday morning after the wireless device maker reported disappointing revenue and unit shipments for the fourth fiscal quarter. Despite a strong jump in earnings for the period, RIM shipped fewer units of its popular BlackBerry smartphone than many analysts had expected. The company blamed the miss on inventory adjustments at wireless carriers and a higher mix of lower-priced devices being sold during the quarter. – Marketwatch

EADS vs. Boeing: Who's Got the Advantage? Back in February 2008, EADS and Northrop Grumman(NOC) had together beaten Boeing(BA) for the roughly $35 billion contract to supply refueling tankers to the U.S. Air Force. It was a big upset for Boeing, but Boeing's loss ended up being short-lived. The deal was later snuffed out when government auditors decided to uphold Boeing's protest. Northrop -- expressing outrage that the reversal, and subsequent rebidding process, was too friendly to Boeing -- decided in March to opt out of the latest bidding race to supply the Air Force's next generation of aerial-refueling planes. – TheStreet
