Example Input: (CNN) -- Boeing resumed testing Monday of its 787 Dreamliner in an effort to receive certification from the Federal Aviation Administration, a company spokeswoman said. The certification tests come two months after a fire on board one of the planes caused a power failure during a test flight. Boeing halted tests after the November 9 incident. Boeing resumed in-house testing of the jet on December 23, and the FAA certification tests began Monday, said Boeing spokeswoman Lori Gunter. Once the plane meets FAA approval, Boeing can begin filling orders for nearly 900 jets from around the world. The Dreamliner is Boeing's next-generation passenger jet. It is touted as a highly fuel-efficient aircraft made largely with composite materials. Boeing suspended test flights after the fire during a flight near Laredo, Texas, in November. The crew used backup systems to land the aircraft. Engineers determined the problem started as a short circuit or an electrical arc in a power distribution panel, most likely caused by foreign debris, Boeing said.

Example Input: Mexico City, Mexico (CNN) -- What was Hurricane Karl weakened Friday to a tropical storm after making landfall, but the heavy rain it spawned could still cause mudslides and flash floods in the Mexican interior, forecasters said. Karl was downgraded after coming ashore as a Category 3 hurricane about 10 miles (15 kilometers) north of Veracruz, Mexico, CNN's satellite and radar estimates showed. The storm is forecast to weaken to a tropical depression later Friday or Saturday and dissipate over the mountains of Mexico on Sunday, the U.S. National Hurricane Center said Friday evening. It added the Mexican government has discontinued all coastal watches and warnings. The storm delivered torrents of rain and fierce winds several hours before it hit land around 11:30 a.m. (12:30 p.m. ET). Photographs sent to CNN's iReport by Ricardo Arcaraz, who lives in Veracruz, showed heavy rain and trees on top of power lines. He reported widespread outages. Maximum sustained winds later weakened to around 70 mph (115 kph) with higher gusts, according to the Hurricane Center. Karl, located about 75 miles (115 kilometers) east of Puebla Mexico, was moving west-southwest at about 9 mph (15 kph), it said. Satellite images and surface observations from Mexico suggest Karl is weakening rapidly as it passes through steep mountains, the Hurricane Center added. High winds remain a threat, though forecasters said they will likely weaken too in the coming days. The homes of at least 3,000 families in central Mexico were damaged, the state-run Notimex news agency reported. "Tropical storm force winds are occurring in a small area near the center. These winds will continue to spread inland along the track of the center tonight but should decrease rapidly as Karl weakens," the Hurricane Center said. Potentially dangerous rain also was forecast. "Karl is expected to produce rainfall accumulations of 5 to 10 inches across portions of south-central Mexico, with isolated amounts of 15 inches possible in the mountains," the center said. "These rains could cause life-threatening flash floods and mudslides." Within the past day or so, some 8 inches of rain has fallen in Veracruz, according to CNN meteorologist Brandon Miller. Some local flooding was already reported, the Mexican Interior Ministry said. Officials closed some roads and urged evacuations for large, low-lying areas in Veracruz. Mexico's National System for Civil Protection issued a red alert, the highest level, for central and southern Veracruz. An orange alert was in place for northern Veracruz and the states of Hidalgo, Tlaxcala and Puebla. A yellow alert was issued for the states of Tamaulipas, San Luis Potosi and Oaxaca. Mexican President Felipe Calderon also sent a warning Friday morning on his Twitter account. "An alert for Hurricane Karl in the nation's central states," it said, adding that Karl "could convert to a Category 4. It will enter through Veracruz around midday." Texas could be spared any major problems because a storm surge occurs only near the landfall location, said CNN meteorologist Sean Morris. Coastal flood advisories have been issued for south Texas, which means forecasters expect a small amount of coastal flooding but nothing serious, Morris said. A larger threat to south Texas will come from several inches of rain that could cause flooding and mudslides. The area could see as much as 4 inches by Sunday, with isolated amounts of up to 6 inches in far southern Texas. CNN meteorologists Brandon Miller and Mari Ramos contributed to this report.

Example Input: San Francisco (CNN) -- The three largest U.S. cellular carriers by subscribers sell the latest iPhone, and next week, eighth-place C Spire Wireless will join the group. Some people were taken aback this week when C Spire, which only has stores in Mississippi, Southwest Alabama and Southwest Tennessee, announced that it will begin carrying the iPhone 4 and 4S on November 11. Among those grumbling over the news were some of T-Mobile USA's 33.6 million subscribers. How, they asked, could a regional carrier get the coveted product before one of the big four? C Spire's infrastructure is based on a cell standard used by Verizon Wireless and Sprint Nextel, which now both have the iPhone, but it is not common in other countries. C Spire, formerly Cellular South, has a deal with Verizon so that customers who travel outside of its Mississippi home base can still make calls. Since C Spire's network uses the same underpinnings and antenna bands as Verizon, Apple did not have to make modifications to its phones beyond what it already did for Verizon when it launched there in February. An Apple spokeswoman confirmed that C Spire would begin selling the phone next week, but she did not respond to a question about whether the company needed to modify the hardware. The iPhone 4S, Apple's newest gadget, uses a special antenna receiver from Qualcomm that works on typically incompatible networks. "IPhone 4S is now a world phone, so both GSM and CDMA customers can roam worldwide on GSM networks," Bob Mansfield, Apple's head of hardware engineering, says in a promotional video. T-Mobile's network runs on the global standard called GSM. AT&T Mobility also uses GSM. That's what makes T-Mobile an attractive takeover target for AT&T, which plans to bolster its own network using T-Mobile cell towers, as long as the merger is approved. (C Spire, along with Sprint, are suing to block the acquisition, saying it will reduce competition.) While AT&T and T-Mobile use the same basic network infrastructure, their cell signals operate on different antenna bands. That prevents T-Mobile from easily making iPhones run on its network. When asked why C Spire got the iPhone before T-Mobile, Brad Duea, a T-Mobile senior vice-president, smiled, having likely fielded the question before. "The iPhone already works with their bands," he said in an interview on Wednesday. "They didn't have to change anything." Since the original iPhone came out in 2007, owners have been able to take the devices to T-Mobile, swap out a SIM card and use them on the network. But as Apple has added 3G and faster data speeds for AT&T, the unofficial T-Mobile iPhones -- more than a million in all, T-Mobile has said -- have not been able to exceed 2G speeds. AT&T's and T-Mobile's 3G and so-called 4G networks operate on different bands. Another T-Mobile executive, Cole Brodman, recently addressed the issue publicly at a conference and in a letter to customers, though not in great deal. Executives say that, while they'd like to have the iPhone, Android is a fine alternative to the iPhone.
Example Output:
C Spire Wireless will be the fourth U.S. carrier to get the iPhone .
T-Mobile, the fourth-largest carrier, still has no plans to carry it .
C Spire operates on the same network bands as Verizon .
