Business Insider quotes On App.net designer Nevr Mrgn as stating that "this is probably the biggest change Apple has ever made to one of its beta software releases. It's a complete change of heart from Jony Ive, Apple's leading designer." The lightweight font was one of the biggest criticisms of the new iOS.
The report states that Ive's willingness to change the font shows he's willing to hear constructive feedback and adapt. If true, then we should be seeing some of Apple's iOS 7 icons change, as the feedback we've received thus far is that there are a great number of the icons that Apple fans really despise. One of the most hated is the new "Setting" icon highligted in this report which one fan called "truly asinine."
