Cisco's Wireless Networking Business Unit doesn't actually talk so much about wireless networking these days. Increasingly, its message aimed at IT groups is about the broader concept of "mobility."

The change, not only for Cisco but its rivals, reflects the fact that mobile workers are no longer focused simply on replacing an Ethernet cable with a Wi-Fi signal and being able to carry their corporate laptop to the conference room. The real question has become: what can they, and the company, and the company's customers, now do once they've made that replacement?

If you're a Verizon customer upset that your next smartphone contract won't include unlimited data, Sprint would like to remind you that you have an alternative.

The next iPhone, which may or not be called iPhone 5, will have a 4-inch screen according to several unidentified sources cited in news stories this week.

An array of bloggers and technology commenters are already accepting these mainstream media accounts as confirmation of the long-rumored big-screened phone.

It seems that your boss doesn't want you to launch digital birds at evil green pigs during office hours.

Research released today by mobile device management firm Zenprise found that Angry Birds was the most-blacklisted application among users enrolled in its Zencloud MDM service. Other mobile apps that companies blocked their employees from using at work include Facebook, Google Play, Dropbox, YouTube and Skype, Zenprise found. Interestingly, Zenprise also found that Skype was the most whitelisted app among its customers, thus making it the top app to appear on companies' blacklists and whitelists.

Given its very recent attempts to merge with AT&T, you would think T-Mobile wouldn't be a vocal proponent of maintaining competitive balance in the wireless industry.

The reality, however, is that T-Mobile has had no issues repositioning itself as a champion of small carriers everywhere in its vocal opposition to Verizon's proposed deal to purchase spectrum from several major cable companies. During a conference call held by the newly formed Alliance for Broadband Competition Monday, T-Mobile Regulatory Affairs Vice President Kathleen Ham said that her company is opposed to Verizon's prospective spectrum acquisition because of the impact it will have on consumers.

Verizon may be heavily promoting LTE for data, but that doesn't mean it's going to start pushing it for voice services anytime soon.

During an interview with Network World today, Verizon Vice President of Network Hans Leutenegger said that the carrier won't be deploying any voice over LTE (VoLTE) services on its network until late next year at the very earliest. The reason for this, he said, is that Verizon is already largely satisfied with its current voice network and doesn't see the need to push both handset manufacturers and its own customers to use a new technology just yet.

Samsung executives claim that their new Galaxy S III was "enhanced with nature and human emotion." While we can't exactly verify that claim, we can take a look at some of the specifications and features on Samsung's latest smartphone. (See also "Samsung Galaxy S III: A Visual Tour.")

If you've ever dreamed of using Verizon's LTE network as your home broadband connection, now you can.

But it'll cost you.

The last couple of years have obviously not been kind to Research in Motion, which is why the company has been hoping to generate some much-needed positive buzz by unveiling portions of its upcoming BlackBerry 10 mobile operating system this week.

Before we get into reactions to BlackBerry 10, though, let's take a look at just what RIM is highlighting with its shiny new OS. The two big features to come out of this week's BlackBerry World conference so far have been a new camera system that is capable of "rewinding" photos to seconds before you took them so you can have more choice in which picture you want to keep if your initial snap doesn't turn out right, and a new touch keyboard system that lets users swipe backward to delete whole words and that adapts to users' typing habits in a manner similar to the BlackBerry PlayBook's QNX-based keyboard system.
