Apple just released iOS 7.0.4. The update, which measures just 33.5MB in size on our iPhone 5s, provides fixes for FaceTime that should enhance stability. There are also other bug fixes, according to 9to5Mac. You can update your iOS device by visiting the settings panel now, where the software can be downloaded over the air. Side note: Oddly, as we’re checking around the TechnoBuffalo offices, the download seems to vary in size across devices, even across similar iPhones.
