This hack https://github.com/Financial-Times/o-grid/blob/master/src/scss/_main.scss#L489 to suppress flexbox in old ios, blackberry etc, has now been tackled properly by autoprefixer's flex: 'no-2009' option. If this is added in OBT then the hack can be removed and display:flex can be used confidently in other components too.
