Samsung just recently announced they will be releasing two dual-SIM versions of the Galaxy Y in Q1 2012, the Galaxy Y DUOS and the Galaxy Y Pro DUOS.
Galaxy Y DUOS
The specs have the Galaxy Y DUOS sporting a bigger 3.14” display than the original (3”), 3MP camera (instead of 2MP), slightly larger dimensions at 4.32” x 2.36” x 0.47”, 4GB onboard and of course 2 SIM slots.
Galaxy Y Pro DUOS
The Galaxy Y Pro DUOS has the same QWERTY keyboard as the original, virtually identical dimensions to the original, 3MP camera (over the 2MP), 4GB onboard and the 2 SIM slots.
There really doesn’t seem to be any need to upgrade unless you need the dual-SIM functionality. No word on which carrier these will be appearing on.
