Verizon Ending Unlimited Data Plan In July

We are closer to reaching the end of Verizon Wireless’s limited-time offer of unlimited data, says the Wall Street Journal‘s AllThingsD. The website reports that the wireless carrier plans to introduce new tiered pricing plans next month for new smartphone customers — including those buying Apple’s iPhone 4.

If true, the report hardly comes as a surprise. Back in January, when Verizon became the second carrier in the U.S. to offer iPhone service, the company said it would offer subscribers a $30-a-month unlimited data plan for the iPhone’s launch, but highlighted the fact that the offer was for a limited time only.

TSMC May Beat Intel To Market With 3D Chip

Taiwan Semiconductor Manufacturing Co. is competing with Intel to become the first technology firm to offer three-dimensional chips that boost the density of transistors in a single semiconductor by up to 1000 times.

TSMC, the world’s largest contract chip maker, could make its first 3D chips commercially available before the end of 2011, according to a person close to the situation who wishes to remain anonymous.

The time frame for TSMC matches the end of 2011 schedule that Intel has set for the launch of its 3D Tri-Gate chips, which the company expects to be the world’s first commercial 3D chip and the most significant advance in chip technology since the development of the chip transistor in the 1950s.

With several layers of silicon stacked together, a 3D chip can achieve performance gains of about a third while consuming 50% less power. For this reason, 3D chips are particularly well suited to power new generations of mobile devices such as tablets and mobile phones, businesses where Intel has so far failed to establish a significant presence.

“This is definitely a new business opportunity for TSMC,” said Shang-Yi Chiang, senior vice president for R&D at TSMC, in an interview. “We are building a patent portfolio now.”

3D chips are expected to solve a number of problems for chipmakers who are aiming for performance increases in ever-smaller chips. As transistor density rises, the wires connecting them have become both thinner and closer together, resulting in increased resistance and overheating. These problems cause signal delays, limiting the clock speed of central processing units.

“3D chips look more attractive because of their greater density,” Chiang said. “However, it is more difficult to make them because of the testing issues. If you have five stacked dies and one of the dies is bad, you have to scrap the whole thing.”

Verizon Adds LTE Network To More U.S. Cities

Verizon Wireless announced 19 more cities that will get its faster 4G wireless network service starting Thursday, bringing the total to 74 metropolitan areas.

San Francisco and Detroit, already on Verizon LTE since last December, will also see the existing LTE network in those cities expanded, Verizon said in a statement.

The new 19 LTE cities include several state capitals such as Sacramento, Calif., Hartford, Conn., Boise, Idaho, Harrisburg, Pa., Indianapolis, Ind., Salt Lake City (with Ogden), Utah; and Madison (with Milwaukee), Wis. The full list of cities is on Verizon’s website.

This news comes as competitor AT&T is scheduled to launch LTE 4G service in five cities in the U.S. this summer: Atlanta, Chicago, Dallas, Houston and San Antonio.

Rumors have also surfaced that Sprint will begin adding LTE service to its existing nationwide WiMax 4G capability, partly to support a future LTE-ready iPhone, although Sprint has not confirmed those reports.

T.I. Blames Nokia For Lower Revenue

Texas Instruments has revised downward its revenue forecast for the second fiscal quarter due to a slackening in demand for its products from Nokia.

TI said its lower revenue projection is directly related to the market performance of Nokia, which has been experiencing its own troubles. The handset maker last week projected lower sales of devices and services due to lower average selling prices and fewer buyers of its phones.

TI is now forecasting revenue of $3.36 billion and $3.50 billion for the second fiscal quarter ending on June 30, down from $3.41 billion to $3.69 billion the company forecast on April 18 when reporting first quarter fiscal results.

“I would say characterizing as the bulk of it being Nokia is probably understating. Probably being closer to say all of the change in our … middle-of-the-range update versus what we were previously [projecting] was associated with that customer,” said Ron Slaymaker, vice president and head of investor relations at TI, during a revenue forecast conference call that was webcast on Wednesday.

Nokia Expects Windows Phone Before EOY

Nokia has “increased confidence” that the first of its smartphone devices to run on the Windows Phone platform will ship by the fourth quarter, the company said on Tuesday.

Nokia’s CEO Stephen Elop is putting his full weight behind getting a Windows Phone-based product out for the important end-of-year holiday shopping season, in order to help turn around the company’s smartphone fortunes. The company’s teams are aligned around that goal, he said in a statement.

The company won’t reveal ship dates until closer to when the first phones arrive, but the pressure is on to deliver the devices this year, Elop said when the company announced its first quarter results.

Nokia will have several more opportunities to divulge more information shortly. On June 21, Elop will give a presentation at the Connection 2011 Conference, which is organized in conjunction with CommunicAsia 2011 in Singapore. He will give an update on the company’s partnership with Microsoft, and set the stage for a number of product and service launches, according to the program.

Verizon To End Unlimited Mobile Data Plan

If you have a smartphone with an unlimited data plan on the Verizon Wireless network, get ready to mourn the end of those good times.

Verizon will put the kabash on its unlimited smartphone data plan some time this summer, according to comments made by the carrier’s chief financial officer. Speaking at the Reuters Global Technology Summit on Thursday, Verizon CFO Fran Shammo stated the company will soon roll out new tiered pricing plans and altogether eliminate the current $30-a-month unlimited option.

According to Reuters, which reported the news, the move is designed to “force heavy data users to pay more for mobile data.”

Visa Digital Wallet Coming

Visa Inc, the world’s largest credit and debit card processing network, is designing a digital wallet that people can use to pay for things on the Internet or with their phones instead of with traditional plastic cards.

The network said on Wednesday it is collaborating with several large U.S. and international banks to create the wallet. Its partners include US Bancorp, PNC Financial Services, Regions Financial, BB&T Corp, Toronto Dominion’s TD Bank and the U.S. arm of Barclays PLC.

The “digital wallet” will store the banks’ customers’ credit and debit card account information, both for Visa cards as well as other cards. People can use the wallet to pay for things online or in stores, Visa said.

The network will also have to convince merchants to put a new “one-click” button on their websites, so that potential customers can use their Visa digital wallets to buy things by clicking the button instead of by manually entering all of their account information every time they want to make an online purchase.

Banks, mobile phone operators and networks like Visa are all trying to gain territory in the small, but high-potential market for U.S. mobile payments. Last week Isis, a separate mobile payments venture run by three of the top four U.S. carriers, said it had modified its initial goals and was now open to working with Visa and MasterCard as it introduces its own mobile wallet.

Jim McCarthy, Visa’s head of global products, told Reuters in an interview on Wednesday that mobile payments in the United States “will more easily take off” from people using their smartphones’ browsers to buy things online.

EBS Coming To Your Smartphone

In the event of local and/or nationwide disasters, wireless carriers will soon begin alerting the public by sending emergency SMS text messages to mobile phones.

AT&T, Sprint, T-Mobile and Verizon Wireless have all agreed to a participate in this new Emergency Broadcast System alert method. It  will initially be rolled  out in New York and Washington, D.C., later this year, and nationwide next year, in April at the earliest.

The emergency text messages will cover public safety threats, Amber Alerts for missing children, and messages from the president, the New York Times reports. Messages will be free for customers, who can opt out of them all except the presidential messages.

We don’t expect the alerts to be frequent,” Julius Genachowski, chairman of the Federal Communications Commission, told the Times. “They will be reserved for when they are truly needed, for tornadoes or for disasters like 9/11.”

Genachowski said the emergency texts will look different from ordinary messages, making them more difficult for hackers to infiltrate or fake. They’ll probably appear directly on the screen, along with a special vibration or other signal. No word on how closely they’ll resemble the tone and color bars of the current Emergency Broadcast System for televisions, or whether users can expect “this is a test” messages on a regular basis.

Google Facing DOJ Probe

Google is under investigation by the U.S. Department of Justice concerning practices within its advertising program, and has set aside $500 million for a potential resolution fund, the company said in a regulatory filing on Tuesday.

In its quarterly report filed with the U.S. Securities and Exchange Commission, Google said that in May it accrued $500 million for the three-month period ended March 31, 2011 in connection “with a potential resolution of an investigation by the United States Department of Justice into the use of Google advertising by certain advertisers”.

Although it cannot predict the ultimate outcome of the matter, Google said that it believes that it will not have a material adverse effect on its business, consolidated financial position, results of operations, or cash flows.

The company did not explain why the charge had been taken retrospectively on its first quarter earnings. It is also not clear to whom Google would have to make the payment in the event of settlement.

Google declined to comment, stating that it was a legal matter. The company has updated its first-quarter results press release on its web site, to reflect the new charge.
