Looks like Taiwan is getting all sorts of rumors tonight, which must make those folks happy (or disappointed if proven false). The latest comes from Sogi.com.tw, which evidently is a reputable source for phone rumors and news. But instead of a Mango update, this is about a new Mango phone.
They're reporting that the Fujitsu IS12T, that super cool and waterproofed Mango phone, will be hitting Taiwan "next month". No word about where this info has come from, but others seem to put some faith in it and lets be honest, it's hardly a stretch of the imagination, what with Japanese and Chinese support being available in Mango.
