RSS readers proliferate in the App Store. But for a full solution, one of the best is NewsGator's free NetNewsWire, which syncs with feeds you specify through the company's free online Web portal. As you view items on your iPhone, articles are conveniently marked as read on your PC or Mac. You can also save items for later reference using the clipping feature. These, too, are available when accessing NewsGator from your Mac or PC.
