A rather innocuous OTA update (T989UVLH1) for T-Mobile's Galaxy S II was announced today, with a 2-line changelog that, on the surface, probably won't excite anyone:
That's the whole thing. But that little Isis mention is easy to overlook - this is the first phone to officially indicate (if indirectly) support for the carrier-backed mobile payment system. Unfortunately, we don't have a T-Mobile Galaxy S II in order to check if this update actually brings the Isis app itself, or is merely in preparation for support. Either way, it implicitly confirms that this phone will be Isis-ready.
