Remember the leaked GT-i9502, that dual-SIM variant of the Galaxy S 4 that ultimately confirmed many rumors? That smartphone is at last exists beyond a collection of photos, as Samsung just launched it for China Unicom customers. The support for an extra cellular line is naturally the highlight, although there's another perk for GS4 connoisseurs: the i9502 has the same 1.6GHz Exynos 5 Octa processor as the i9500, which might eke out more performance than the Snapdragon 600 models. There isn't any word on whether or not the i9502 edition will leave China, although we wouldn't count on European or North American editions when there isn't LTE inside to please 4G-obsessed carriers.
