Sprint Nextel abandoned plans to sell a 4G version of the BlackBerry's PlayBook, meaning the 4G tablet currently isn't supported by any of the three largest U.S. wireless carriers.

The next iPhone will include lots of goodies, but support for next-generation 4G wireless networks still isn’t one of them, Sterne Agee & Leach analyst Shaw Wu wrote in a note to investors Tuesday. The new iPhone will get a dual core processor, a “slightly larger” display, and a thinner bezel. No 4G, though.

Bidding to differentiate itself in the increasingly competitive tablet-computer market, Samsung Electronics plans this year to launch an Android-based tablet running on fourth-generation network technology.

AT&T has announced the first cities that will get its 4G LTE service. These cities, Dallas, Houston, Chicago, Atlanta and San Antonio, will see AT&T's version of LTE this summer. Verizon's LTE service, which launched in real (non-beta testing) form late last year, though sans handsets, has vowed to get its LTE service into 175 markets...

Verizon Wireless said its high-speed 4G data network was suffering an outage, a black eye for the carrier that prides itself on the quality and stability of its network.

A next-generation wireless smartphone network can stream video, blaze through the Net ... and steer your car into a ditch? Super-fast “fourth generation” networks carry data at speeds of up to 1 Gigabit per second. But the new network from LightSquared may take the high-flying GPS network to zero Gbps -- potentially preventing air-traffic control towers from keeping track of aircraft, the military from accurately relaying locations or ambulances from showing up at the right house after a 911 call.

We got the chance to test T-Mobile's newest, fastest phone, the Galaxy S 4G, and decided to see how fast some other top 4G-labeled phones were. It turns out, not all 4G is equal.

To the average consumer, the intricacies of the wireless technologies used by cellphones and other mobile devices are confusing. Fortunately, cell phone carriers have made it easier on us by inventing the “G,” a nebulous standard that makes people think they understand what they’re getting when they sign up for that two-year contract. The bad news: The carriers themselves typically don’t care about what a 3G or 4G network should actually be. And now, as proof of concept, AT&T has re-branded their existing 3G network as a 4G network.

The first portable devices announced for Verizon Wireless' new, high-speed wireless data network are a smart phone and a tablet from Motorola, both designed to take advantage of network's speed with cameras for videoconferencing....

AT&T, facing a marketing challenge by competitors' 4G wireless service claims, accelerated its own network upgrade plans and said it would release devices for its own fourth-generation network.
