Apple software update for iPhone

Apple is certainly cranking out software updates for the iPhone, as the latest will be the third one since its June release. This new update supposedly throws in new features while improving the overall stability for the phone’s Mac OS X operating system. If you’re an existing iPhone user who wants to hook up to the Applie Store via WiFi, you’ll be greeted with a dialog box asking you to upgrade your firmware. Other new additions include support for the Wi-Fi iTunes Music Store. I wonder how this update will affect unlocked iPhones?
