Microsoft: Windows OS Mango is imminent

Microsoft has confirmed the next iteration of the Windows Phone OS, known as Mango, will be released in the next one or two weeks.

Otherwise known as Windows Phone 7.5, Mango will be delivered alongside a software update from each handset manufacturer, so the firmware matches up with the OS to ensure the transition is smooth, said Eric Hautala, in the Windows Phone Blog.

Hautala, general manager customer experience engineering for Windows Phone, also took the opportunity to warn users of downloading unofficial versions of Mango.

"Since your phone requires the proper firmware to function as designed, my advice is simple: steer clear of bootleg updates and homebrew tools," he said.

"I know you're eager to get your hands on the next release of Windows Phoneand everyone involved with Windows Phone is equally excited and eager to deliver it to you. Please hang onwe're almost there."

The timing of Mango's launch will pique the interest of onlookers, as Apple is expected to launch the iPhone 5 on 4 October.

Later in the month, Nokia is expected to introduce its first Windows Phone devices. It is believed CEO Stephen Elop will take to the stage during Nokia World 2011 in London and unveil devices featuring the Mango OS.
