AT&T mobile subscribers in Seattle and Portland can now grab their own slice of LTE.

The carrier announced today that it has turned the switch on its high-speed network for customers in both cities. That brings AT&T's total number of LTE-enabled markets to 72.

Earlier this month, the company activated 4G LTE access in Anchorage, Alaska, Bakersfield, Calif., Jacksonville, Fla., Modesto, Calif., Omaha, Neb., Syracuse, N.Y., and Bridgeport, Conn.

An AT&T spokesman told CNET that the company plans to reach a total of 100 cities by the end of 2012 and complete … Read more

Apple has taken a wait-and-see approach to 4G LTE, and that may pay off for the iPhone 5.

While LTE on Verizon's network has become a standard offering for Android phones over the last year or so, Apple CEO Tim Cook has resisted -- until Wednesday.

Cook always said pretty much the same thing: iPhone-use LTE chipsets aren't good enough yet for Apple.

And he had a point. Previous generations of LTE tech had power-consumption and chip-integration tradeoffs. Plus, Verizon's build-out of LTE has been steady but slow. (It just reached an area near my stomping grounds, … Read more

The ghost of Apple's iPhone 4 "antennagate" looks to be haunting the iPhone 5.

The reason simultaneous voice and data capability on 4G LTE isn't possible on Sprint and Verizon simply seems to be the new device's hardware.

CNET reported earlier today that the iPhone 5 models for both Verizon and Sprint don't support data-use and voice simultaneously while on 4G LTE networks -- meaning that if users make a voice call, they'll also need to be on Wi-Fi to pull data inside their apps, including the Safari Web browser.

It appears that AT&T will still have an edge on rival carriers when it comes to one key iPhone 5 feature.

The models for both Verizon and Sprint won't let you do other data-hungry tasks while making a phone call on 4G LTE networks. When you're making a voice call on either of the two networks, you'll need to be on Wi-Fi if you want to pull data inside apps, including the Safari Web browser.

"The iPhone 5 was designed to allow customers to place a voice call on the Verizon Wireless network, while … Read more

Today, Sprint and Samsung trotted out the Samsung Galaxy Victory 4G LTE, a phone it's billing as a stepping stone for smartphone first-timers.

The Android 4.0 Ice Cream Sandwich device features faster data speeds, a 4-inch display, and a 1.2GHz dual-core processor. There's also a 5-megapixel camera, a 1.3-megapixel front-facing camera, and Sprint ID, which lets you load entire profiles based around a theme.

NFC is on here, and Google Wallet will be ready to go for those seeking an opportunity to pay for products with a tap, assuming they're eligible to tie it … Read more

Apple should regain its spot as the smartphone leader courtesy of the iPhone 5, says J.P. Morgan analyst Mark Moskowitz.

Unveiled yesterday at Apple's launch event, the new iPhone could surpass the sales of rival handsets such as Samsung's Galaxy S3 for a variety of reasons, according to the analyst.

The new phone is thinner, lighter, and faster than its predecessor, Moskowitz said in an investors note out today. It also throws in a 4-inch screen and support for 4G LTE. But the iPhone 5's design and battery should help it avoid certain problems faced by … Read more
