Rejoice iPhone photogs, the newest version of Instagram is now available! The immensely popular app has just updated to version 2.1 and boasts some impressive new features.
Among them, 2.1 offers a UI redesigned for simplicity with an improved header and menu buttons, a new “Sierra” filter, and Lux—an automatic process that brightens and sharpens dark, drab photos with a single tap not unlike HDR. Instagram is still free and available for download at iTunes. [Instagram via iTunes]
