In London today, Nokia revealed the first fruits of its partnership with Microsoft: a pair of Windows Phone handsets, the Lumia 800, codenamed Sea Ray; and the Lumia 710, codenamed Sabre. The 710 has a 3.7" LCD screen, 8GB flash memory, and a 5MP camera with an f/2.8 aperture. The 800 has a 3.7" AMOLED screen, 16GB flash memory, and an 8MP camera with an f/2.2 aperture. Both are powered by 1.4GHz processors with 512MB RAM, and both run Windows Phone "Mango". Both handsets also use tiny micro-SIMs instead of the normal mini-SIM.
