dual sim card samsung phone

I was thinking to look for a new unlocked phone with dual sim card in order easier for me to carry instead of two cell phones. I feel very incovenience because I also have to bring two different type of charges for charging. But, I still need to have a two lines because I have my own personal lines which is used for part time business after the working hours. Hehehe… I was thinking to get a new model cell phone released by samsung as I heard from the radio recently. Any idea what is the model of that?
