iphone 4 IOS 7.1.2 Want to delete all the songs from the phone (taking up too much space) And, insert a playlist I have on itunes. Have tried deleting from itunes with phone plugged in. Does not respond to delete button on laptop, In itunes Song>Delete is greyed out. Have tried General>Usage>Manage Storage and the Music app is supposed to appear with the option to delete, but it does not. Ya, I need a new phone or a different brand - go way.
