While Steve Jobs and Apple.com (the main US version of the site) say iOS 4.1 for iPhone and iPod touch is coming sometime "next week", Apple.com/uk is cheeky enough to put a date on it -- Wednesday, September 8.
Download the iOS 4.1 Software Update. Available on 8 September.
New highlight features include Game Center, iTunes TV rentals, Ping social music network, HDR photography, HD YouTube video uploads, and AVCRP stereo Bluetooth support (see our quick start video up top).
