It’s finally official — China Unicom will be carrying not one but two models of the iPhone sometime in Q4, having inked a three-year deal with Apple. Unceremoniously announced during a fiscal report, China Unicom hasn’t yet specified which iPhone models it will be offering or at what price points. The smart money is likely on a custom Wi-Fi-free version of the 3GS and the tried and true 3G. China Unicom will begin hawking iPhones sometime in Q4 and odds are pretty good that it’ll sell like hotcakes. Interestingly, it is being reported that the China Unicom deal is not exclusive, meaning this plot could get a whole lot thicker in the near future.
