Listen to the current daily podcast: A federal judge has ruled invalid a proposed settlement in the NTP/RIM patent-infringement case and Research In Motion says it is working on ways to keep BlackBerry service up and running just in case the judge shuts it down. Also, New York Attorney General Eliot Spitzer's office berated Sony yesterday for not making good on its promise to pull its rootkit-infested CDs from store shelves. Finally, Microsoft has made a bevy of announcements, including when Vista's features will be ready, and sources say the company is arranging to have more of its internal IT development work done offshore.
