Over the weekend photos of a yet to be announced Sony Ericsson smartphone leaked (see below), with some believing that this could be the first dual-core smartphone from the company. As reported by Phonearena, rumors are suggesting that the new device could have the name of Sony Ericsson Xperia duo, which could further point towards it being dual-core but that is complete speculation. With the Sony Ericsson Xperia mini and the Sony Ericsson Xperia mini pro just being released in recent weeks it remains to be seen whether these rumors prove to be legit.
