Microsoft: Windows Phone 7.5 Mango arriving soon

Windows Phone 7.5, codenamed Mango, has been on the cards for an age now, with rumoured launch dates coming and going, but Microsoft's Eric Hautala has stepped in with official word: it's coming 'soon'.

The Mango update has been rumoured to be 'just around the corner' for months, but when we saw devices at IFA in Berlin running the code it seemed closer than ever. Since getting back to the UK, however, Microsoft has been silent on the topic, and until it makes the launch official the hands of OEMs like Dell are tied.

Things seem to be finally moving, however. In a post to the Windows Phone Blog, team member Eric Hautala promised that the update - which brings some much-needed extra functionality to Microsoft's smartphone platform - will be rolled out within the next couple of weeks.

"For months, we and dozens of our partner companies have been laying the groundwork for the Windows Phone 7.5 update - and making solid progress," claims Hautala. "As a result, we now expect to start rolling it out in the next week or two."

That's good news for those waiting for the official release, but Hautala also has a warning for those who are getting impatient: don't install leaked ROMs.

"During the official Windows Phone 7.5 update process, every Windows Phone will also receive software from the handset manufacturer," Hautala explains. "This matched and paired firmware has been painstakingly tuned so your phone - and apps - work with all the new features of Windows Phone 7.5. Since your phone requires the proper firmware to function as designed, my advice is simple: steer clear of bootleg updates and homebrew tools."

For those that have already taken the plunge and installed a third-party ROM, Hautala's message has a hidden warning: you may not find it easy to switch from the unofficial build to the final release of Mango without a full factory reset.
