LEADING THE DAY: The House commerce committee has asked the Internet Corporation for Assigned Names and Numbers to delay its plan to expand the number of top-level domains on the Internet. In a letter to ICANN, a bipartisan group of six committee members said that they share the concerns of some businesses that the expansion does not have adequate protections in place for copyright holders.

“Given these widespread concerns, a short delay will allow interested parties to work with ICANN and offer changes to alleviate many of them, specifically concerns over law enforcement, cost and transparency that were discussed in recent Congressional hearings,” the letter read.

Microsoft preps for final CES : Microsoft said Wednesday it won’t participate in the world’s biggest tech convention, the Consumers Electronics Show, after the January 2012 show.

Carrier IQ: Motorola and T-Mobile responded to requests from Sen. Al Franken (D-Minn) for more details on how they use Carrier IQ software.

In its letter to Franken, T-Mobile revealed that it uses the device on some of its premium smartphones including the HTC Amaze and the Samsung Galaxy S II. It estimates that 450,000 of its customers “use devices that contain Carrier IQ’s diagnostic software,” which collect some information, such as the telephone numbers a user dials and the phone numbers from incoming calls. T-Mobile does not collect the content of text messages sent or received, the content of e-mails sent or received, the URLs of Web sites visited, information from users’ address books or any other keystroke data, the company said. Motorola said it installs software on four models at the request of its carrier partners.

The Journal report also listed that figure.
