While Windows Phone's share of the global smartphone market has been stagnating at around 3% for some time, there's no denying the astonishing momentum that Microsoft's mobile efforts have been gathering in recent weeks.

In the last week alone, we've seen two new Windows Phones from Cherry Mobile in the Philippines; a new handset from TrekStor that will go on sale in November; and the first Windows Phone with a 64-bit processor from Alcatel OneTouch. We also got a much clearer look at BLU's striking new handsets, the $89 Win JR and $179 Win HD - the first of which has already gone on sale.

Today, it seems that we can add another brand to the growing list of companies set to offer Windows Phones. A new Windows Phone - called the GoFone GF47W - has been spotted from UK company My Go.

My Go offers a range of ultra-affordable tablets, netbooks and e-readers - but so far, its range has not included a smartphone. The new Windows Phone may be its first venture into this category, having been seen on an unlinked microsite hosted on My Go's servers. The page carries a "CONFIDENTIAL - Internal Use Only" banner, which indicates that it is not yet ready for public consumption, and the URL - which includes the word 'project' - suggests that the device remains a work in progress for now.

The device itself is another iteration of the now-familiar 'I7B' reference design from JSR Technology, which has been used by many other brands for their first Windows Phones, including the XOLO Win Q900s, the TrekStor device seen this week, and the Polaroid WinPro 5 that was seen recently.

Its key specs include:

4.7-inch IPS LCD with HD (1280x720px) resolution with Dragontrail Glass

Quad-core 1GHz Qualcomm Snapdragon 200

1GB RAM

8GB onboard storage

8MP rear camera

2MP front-facing camera

7.2mm-thick body

Dual-SIM support

There is one anomaly in the quoted specs - in two places, the device is said to have a weight of just 95g, but at another point, it says that it weighs 130g. The standard device offered by JSR Technology weighs 100g, but brands are free to request modifications and changes to this basic model, to customize it for their own customers - although the My Go spec sheet doesn't indicate any significant deviations from the standard reference design. The only major difference is that the GF47W is said to have a 1GHz quad-core processor rather than the 1.2GHz CPU seen elsewhere.

Nonetheless, the device is still pretty light, and has a decent set of specs for an entry-level handset. Details of pricing and availability are, of course, completely up in the air for now, but stay tuned, and we'll bring you that info when we have it.
