Going way, way back to when Windows Phone 7 Series (ahem) was first announced in February 2010, it was within a few months we saw the first "developer" phones making the rounds. One was the Samsung Taylor (SGH-i707), which of course never went commercial but proved to be a decent device for trying out new software on.
Surprisingly, even this device has managed to get the Mango update, at least according to Nuno Luz, who's a Mobility Solutions Specialist at Microsoft. Posted on his Facebook page, he shows us the screen shot of the Settings for evidence. Makes us wonder if our Toshiba TG01 would get Mango...hmmm.
