Last night, Apple released the first update to the iPhone, software version 1.0.1. The update is only available via iTunes and is automatically applied the next time you sync. If you haven't applied it yet, you might want to do so before the weekend, as the big hack that has been promised for the Black Hat conference in Las Vegas is fixed in this version. Security details are available on the Apple web site. Since the Safari bug that is fixed also affects the Macintosh versions of Safari, Apple released another security update separately.
