The Windows Phone 7 operating system launched last October and it isn’t exactly clear how many users it has. CNET points out that the company said it had sold more than 2 million of ‘em back in January.
No matter how many people are out there using it, though, it will now have a new square-shaped logo, TechCrunch reports, citing Japanese Microsoft developer and "Windows Phone evangelist" Takahashi Shinobu, who posted the WP 7.5 logo on his Microsoft blog about changing his email signature, above.
Our (imprecise) Google translation of his blog post: "Windows Phone logo is new. Writings already 7700 or later Windows Phone 7.5 beta boot logo is this design. Image tiles as you can see the new logo, this logo will be 7.5 Windows Phone later."

Replacing the familiar Windows 7 circular logo (at right) “comes ahead of a major update to the Windows Phone software itself,” according to TG Daily.
Announced in May, the next version, called Mango, will hit Stateside in a few months and “Microsoft hopes it will be a catalyst to really bring in new Smartphone customers as well as existing customers looking for something different,” TG Daily notes.
Part of the logo change is done by setting “the recognizable Windows flag … in a flat tile, symbolic of the software interface,” TG reports. “The previous logo was a circle, which was more in line with Windows Vista or Windows 7 iconography.”
PC Magazine reports that the flat tiles are known as the Metro style user interface and include “red, blue, and orange versions of the square logo.” The first place that will get to see the new logo on an actual phone, though, will be in Japan since Mango will be the operating system on the new Fujitsu-Toshiba IS12T.
In fact, the new Windows Phone square logo was spotted in a Nokia demo back in June, while another eagle-eyed blogger in Japan, Nanapho, spotted the new logo at a trade show and posted some pics online, including this:
