If i am in a social setting i only use my cell phone if its an awkward situation like waiting on a friend at a club. i have seen guys though if they have a really nice expensive phone pull it out to show it off. So i think it goes both ways if u have a expensive phone guys want to show it of kinda like if they have a nice car they always want to show that off to its just another status symbol. As for women using their cell to avoid men i think that’s pretty funny because ive seen it happen couple of times.
