@Riven Probably phones without headphone jacks are those that can no longer be used as regular FM radios - as the antenna was actually the headset (at least that's my experience) - and another reason why phones without the jack suck. Never had a phone with a built-in FM antenna FWIW.
But yea, I do get your point. Phones could do so much more than accessing Facebook, Instagram and posting photos there or something like that.
