Report: iPhone 5 to be a dual-mode 'world phone'

Apple's upcoming iPhone 5 will support access to both CDMA and GSM networks, allowing it to operate in most countries around the world, a source tells TechCrunch.

An unidentified app developer reportedly pulled information from registration logs that show two distinct mobile network codes (MNC) / mobile country codes (MCC). These codes, which are believed to have been entered by testers of a single device using Apple's upcoming mobile operating system iOS 5, are unique mobile network identifiers belonging to Verizon and AT&T, TechCrunch said.

Apple now caters to both companies, but the devices are not designed to operate on each other's networks; Verizon's works on the CDMA standard, while AT&T's iPhone 4 operates on a GSM network, the dominant global wireless technology and the standard in Europe.

While the iPhone 5 has been long rumored to be a CDMA/GSM world phone, Verizon's iPhone has always had this capability, although it's not activated. Teardowns of the device showed that it sports the Qualcomm MDM6600 chip, the same chip that's used in the Droid Pro world phone.

TechCrunch concluded that a dual-mode phone would suggest that the iPhone 5 would not support LTE. However, Apple's latest developer builds for iOS 5 contain a snippet of code that mentions LTE, according to enthusiast site MacRumors, prompting speculation that the company may be testing 4G internally.

The hotly anticipated next edition of Apple's smartphone is expected to be released in October. … Read more

iPhone, iPad boost chip sales for wireless devices

The demand for smartphones and tablets is causing manufacturers to spend more on chips for wireless devices than for traditional computers, says a report out yesterday from IHS iSuppli.

As the tech industry shifts more of its emphasis from PCs to mobile gadgets, the wireless segment is poised to become the leading market for chip buying starting this year.

Manufacturers will buy $55.4 billion of semiconductors for wireless devices this year, a jump of 10.7 percent from 2010, according to IHS. But spending on chips for computers will reach $53.1 billion this year, a gain of just … Read more

Disposable sensor detects heavy metals in humans

Researchers at the University of Cincinnati have created a disposable lab-on-a-chip sensor that can test levels of potentially harmful heavy metals in humans in as few as 10 minutes.

Their work, published in the August issue of the journal Biomedical Microdevices, is co-authored by assistant professor of environmental engineering Erin Haynes, who has also been studying air pollution and the effects of lead and manganese on residents in Marietta, Ohio--home to the only manganese refinery in the U.S. and Canada. (Manganese compounds are used to make steel and other products.)

Manganese is naturally ubiquitous and considered essential both nutritionally … Read more

PC chip shipments flat, but sales up

Shipments of PC processors failed to gain ground during the second quarter, but revenue still inched its way higher, according to data out today from IDC.

For the quarter, worldwide chip shipments rose only 0.6 percent from a year ago and fell 2.9 percent from the first quarter. Sales reached $9.49 billion, a 5.4 percent rise from 2010's second quarter but a 4 percent drop from the first quarter.

"The first quarter of 2011 was better than most first quarters due to the extra calendar week," Shane Rau, director of Semiconductors: Personal Computing … Read more

Different Thunderbolt chip spotted in MacBook Airs

The brains behind the port you'd find on one computer would be similar to the same port on another machine, right? That's not the case when it comes to the Thunderbolt ports on the latest MacBook Airs, which joined Apple's Thunderbolt-equipped club earlier this month.

A report on AnandTech notes that the Thunderbolt controller found on the MacBook Air is a smaller version than the ones found on other Thunderbolt-equipped Macs so far. With other machines, Apple's been using a controller code-named Light Ridge that sports four, bidirectional Thunderbolt channels and two DisplayPort outputs. However the … Read more

New lab-on-a-chip genetic analysis resembles pinball

Researchers have invented a silicone lab on a chip they say could make genetic analysis far more sensitive--not to mention rapid and cost-effective--by routing fluid through microscopic tubes and valves, and allowing individual cells to fall into place much like balls in a pinball machine.

Standard genetic testing involves vast numbers of cells that, when analyzed, provide a sort of composite picture that cannot reveal the behaviors of individual cells.

"It's like trying to understand what makes a strawberry different from a raspberry by studying a blended-fruit smoothie," said Carl Hansen, an assistant professor who led the … Read more

Tilera's 100-core processors take on Sandy Bridge

Tilera has introduced a range of processors with up to 100 cores, aiming to take on Intel in servers that handle high-throughput Web applications.

The chips in the 40nm 64-bit Tilera Gx family, announced yesterday, have between 36 and 100 cores and are intended by the Silicon Valley-based chip design company to compete with Intel's Sandy Bridge range of processors.

"The reason we can go against Sandy Bridge architecture is [Intel's range] was designed for general-purpose [applications], so it has to account for single-thread performance and power-point performance and Windows," Ihab Bishara, Tilera's head of … Read more

Keyport Slide slims down, techs up your keychain

If you're like me and you don't like little sharp metal objects jingling around in your pocket, scratching up your phone, and ripping holes in your pants, you may be looking for a way to manage your keychain. The Keyport Slide aims to do just that, replacing your keychain with a slick looking aluminum chassis that sheathes your keys, creating a solid unit that doesn't jingle around and weighs next to nothing--as long as you aren't carrying more than six keys around at a time.

The Slide measures 4 inches long by 1.25 inches wide … Read more
