Microsoft and Nokia are set to launch the Chinese Lumia 800 ("Lumia 800c") earlier than planned, according to an insider informed WPDang article. The Windows Phone platform itself officially launched yesterday with the goal of regaining markshare by releasing "Tango" and hardware from the likes of Nokia, HTC (Triumph) and ZTE (Orbit/Mimosa).
The Lumia 800c is a CDMA variant of the Lumia handset (think Verizon and Sprint), is set to power Windows Phone Tango, and will be available in black, cyan and magenta on China Telecom. The original date of availability for the Lumia 800c in China was late March / early April. Unfortunately, the Lumia Momentum Map that Nokia has published (and relatively up-to-date) on their website does not display any information regarding the Chinese launch of Lumia Windows Phones.
As well as the 800c, Nokia is also believed to be launching the 710 and the WCDMA version of the Lumia 800 next month. Keep an eye out in the remaining weeks of March for more details surrounding the Lumia 800c.
