Microsoft showed off a number of new Windows Phone “Mango” devices during a Microsoft Worldwide Partner Conference presentation on Tuesday. The unnamed devices were on stage during a Microsoft presentation, and were handled very briefly so the audience could get a quick look at them. Acer’s first Windows Phone was the first device to be displayed, followed by a pink waterproof offering from Fujitsu. ZTE also had a device on stage, but all eyes were locked on a Galaxy S II-like device from Samsung running Windows Phone Mango. Unfortunately, no additional details were shared surrounding any of the aforementioned smartphones. A video of the forthcoming Mango phones follows below.
