Ohh really? Interesting! Admittedly, I ask this because I'm sure my husband is cheating on me, and I've vèn investigating this for a few months now. Many may things not right not normal not as he claims. One being dual messenger... and messaging from more than just the normal parameters. He has this activated. I knew something wasn't adding up with his messages. Before I even knew dual messenger was on his phone activated I knew from my spy cameras something wasn't right about his messages. Seemed like there were messages being exchanged that simply disappear when I sneak on his phone to check. So a copy of the app you say. Most interesting. I suppose the copy will have an identical icon(s). The copy icons could be hidden from view in turn, so one would have to know where to look to open the extra version. Would that be the case?
