He noted that smartphones would be able to send GPS data to Facebook, potentially telling the social media giant where the phone, and likely its owner, is at any time. "So if your phone doesn't move from a single location between the hours of 10 pm and 6 am for say a week or so, Facebook can quickly deduce the location of your home," he said. "We need to ask our legislative representatives to understand that Facebook wants to go from our desktops and browsers right into our home - the place where we need to be private," he wrote. Mark Zuckerberg unveiled Facebook Home at a press conference in California last night. The expected partnership with HTC was also confirmed as the smartphone manufacturer launched the HTC First, which will have Home built in. Our phones are designed around apps, not people. We want to flip that around," Mr Zuckerberg said. He introduced "Chat Heads," a "layer" feature that would allow users to read and send Facebook and text messages without needing to switch back to Home. Facebook Home will be available to install on other Android devices such as the HTC One X and Samsung Galaxy S3 from April 12 in the US. It will be available worldwide "in the coming weeks."
