Two couple of months ago, Microsoft announced that the next version of Windows Phone, codenamed 'Mango', had been finalized, yet no devices running earlier versions of the system have officially obtained 'Mango'. Thankfully, official HTC ROMs have been leaked and made their way onto the Internet, enabling users of the HTC HD7 to run 'Mango' right now, one day after a similar ROM file was leaked for the HTC 7 Mozart.
