The Windows Phone 7.5 “refresh” is nearly upon us, with news of Tango coming to China next week. Of course, we wouldn’t expect a bunch of die-hard smartphone fans to wait until a formal release to start enjoying new software, and the crowd over at the XDA-Developers forums have already cooked-up a pair of custom Tango ROMs, now available for the HTC HD2 and the Samsung Omnia 7.

It seems only fitting that the HD2, the quintessential tinkerer’s smartphone, is among the first of the models to see these new ROMs. These releases build upon previous custom ROMs, so there’s all the benefits of a fully-unlocked operating system in addition to the new Tango changes.

There are a few limitations that might give you pause before installing either ROM, like the fact that Microsoft’s blocking access to the Marketplace until Tango starts officially going out. The ROMs also have their individual bugs, like some messed-up language support or an inability to easily update the software. Still, if you’re curious and you don’t mind those little rough-around-the-edge bits, Tango’s now yours to explore.
