Sprint rolls out 4G WiMax in Los Angeles, Miami, four other cities

The great 4G roll out race is well underway with Sprint already enjoying a sizable head start on rival Verizon. Sprint announced today the launch of its 4G WiMax network in six new markets: Los Angeles; Washington, D.C.; Cleveland; Miami; Cincinnati; and Columbus, Ohio. Sprint’s announcement comes as Verizon is slated to begin rolling out its own 4G LTE network in select cities starting sometime next month.

“We have witnessed a great demand from our customers for 4G speeds, power and capabilities in these cities already and today they officially have it,” said Matt Carter, president of Sprint’s 4G effort. “We are proud to deliver on our commitment to serve our customers and deliver 4G to more major metropolitan areas in 2010.”

Sprint claims the 4G WiMax network allows for faster mobile downloading, video chatting capabilities, and Web browsing “up to 10 times faster than 3G service.” Sprint currently offers several WiMax-ready mobile devices including the Samsung Epic 4G and the HTC EVO 4G as well as computing options in the Dell Inspiron Mini 10 netbook and the Dell Inspiron 11z notebook which are also embedded with 4G WiMax capabilities.

The latest round of roll outs brings the total of number of regions with WiMax coverage to 68 – five more regions than Sprint had originally planned to be operational by this time. Earlier in the month, Sprint launched WiMax in New York City and now that it has added Los Angeles, the company can claim to have WiMax available in the U.S.’s two most populous metropolitan areas.

Construction of the WiMax network itself is actually being carried out by Clearwire, of which Sprint claims to be the majority shareholder. WiMax first launched back in 2008 in Baltimore.

Dec. 1 had previously been set as the WiMax launch date for Los Angeles meaning that users there are seeing 4G coverage a full two days earlier than anticipated. Sprint, no doubt, has been feeling the pressure to keep up the pace of WiMax launches in order to be well entrenched by the time Verizon’s LTE network begins to debut in major markets next month. If Sprint is able to sustain its present pace, then expect to see 4G WiMax coverage coming to San Francisco by Dec. 28.

A dangerous new jailbreak for AI chatbots was just discovered

Microsoft has released more details about a troubling new generative AI jailbreak technique it has discovered, called "Skeleton Key." Using this prompt injection method, malicious users can effectively bypass a chatbot's safety guardrails, the security features that keeps ChatGPT from going full Taye.

Skeleton Key is an example of a prompt injection or prompt engineering attack. It's a multi-turn strategy designed to essentially convince an AI model to ignore its ingrained safety guardrails, "[causing] the system to violate its operators’ policies, make decisions unduly influenced by a user, or execute malicious instructions," Mark Russinovich, CTO of Microsoft Azure, wrote in the announcement.
