NEW YORK -- Investors were taking few chances Friday while waiting for a confidence vote in Greece on the country's embattled prime minister. Stocks fell on concerns that the country might not go through with an austerity program needed to prevent a debt default.

The Dow Jones industrial average closed down slightly after recouping some of the ground it lost earlier. The average fell 2 percent for the week, its first weekly loss since September.

Latest attempt to boost airline fares is scuttled

DALLAS -- The latest attempt by airlines to take advantage of full flights and boost their prices appears to have failed. Most airlines decided not to go along with the higher fares, and those that had raised prices began rolling them back Friday.

US Airways raised fares Wednesday by up to $10 per round trip on higher-priced tickets usually favored by business travelers. Delta had matched the increase but abandoned it Friday. US Airways followed suit.

Maker of Dippin' Dots files bankruptcy papers

LOUISVILLE, Ky. -- Once the self-proclaimed "Ice Cream of the Future," Dippin' Dots is seeking bankruptcy protection, a move aimed at staving off foreclosure on more than $11 million in loans. The company has asked a judge to allow it to use its cash to continue operations while the case plays out.

Regions Bank sued Dippin' Dots in February, alleging the company defaulted on multiple loans. Dippin' Dots said Regions gave it 48-hours' notice that it intended to foreclose on the loans. That forced Dippin' Dots to file for bankruptcy so it can look to refinance.

U.S. Cellular: Thanks but no thanks to the iPhone

Consumers pay $200 for the base model of the iPhone 4S, but Apple charges carriers about $600. Carriers count on making their money back in fees over the life of the contract. U.S. Cellular CEO Mary Dillon told analysts Friday "the terms were unacceptable from a risk and profitability standpoint."

AT&T needs more time to finalize T-Mobile deal

NEW YORK -- AT&T said the deal to buy T-Mobile USA may take until the middle of 2012 to close, three months later than originally envisioned, as it fights antitrust regulators.

AT&T announced the $39 billion deal in March. In August, the Justice Department filed a lawsuit to stop the deal, saying it would cut competition and raise prices. Analysts give AT&T little chance of winning the case.

After reboot, DC Comics pulls in front of Marvel

PHILADELPHIA -- Call it a relaunch bump and jump.

DC Comics overtook long-time rival Marvel for the first time since 2002 after figures for October sales of comic books showed the publisher of relaunched versions of Superman, Batman, the Flash and others gathering 51 percent of the market share for the month compared with nearly 30.3 percent for Marvel.

That's according to Diamond Comic Distributors, a distributor of comics to more than 4,000 retailers worldwide.
