Just yesterday we got our fist look at the Galaxy Y Duos and the Galaxy Y Pro Duos, Samsung’s latest low-cost mobiles designed for users who need an extra SIM card in their phone. Today Sammy Hub reports on the first details of a more up-market version, based on the ever-popular Galaxy S II platform. The I-929 Galaxy S II Duos mirrors the older models in almost every way, though it appears that there’s a little extra junk in the trunk to accommodate dual SIM card slots.

The specs of the Galaxy S II Duos will be familiar to anyone who’s been following GSII variants for the past few months: a 4.5-inch, 800×480 Super AMOLED display, a 1.2GHz dual-core processor and 16GB of on-board storage. Gingerbread is still the order of the day, but Samsung will likely upgrade the new phones to Ice Cream Sandwich shortly after the international version. Unfortunately you won’t be getting your hands on this in the United States any time soon: the phone is bound for China Telecom at the beginning of next year.

It’s a real shame too, since dual SIM phones are perfect for international travel, and for just about anywhere with a spotty signal. T-Mobile users still happy to get cheaper data plans but frustrated with a smaller coverage area could slide in a prepaid AT&T SIM for when their signal goes out. The 1800mAh battery should be able to handle the trip. Perhaps we’ll be seeing this model at import shops soon.
