Cant download shit on IPhone 7

My fuckass Android decided that it's finally time to die, now I'm left with an old family phone and it's an iPhone and lemme tell you how annoying it is to used,you can't download YouTube on that fuckass phone and gotta use safari too what's worse is that I can't listen to music cuz you gotta have a computer to transfer all your music on the apple music and gues what my PC is broken
