Every day, we curate a list of the most interesting tech stories of the day. Today’s list is obviously focused on the launch of Facebook’s new privacy controls, but we also feature interesting stories about Samsung’s ongoing patent spat with Apple, one of the better posts about what the reaction to the HP TouchPad fire-sale really means, and some rumors about a cheaper iPhone 4 that could launch together with the iPhone 5.

To read these stories – and many others – just click on any headline in the embed below that sounds interesting. An overlay will then pop up and allow you to read the story and navigate to all the other ones as well.
