You can download the update via Settings > General > Software Update, or through iTunes. It's a 35 MB download for an iPhone 6, so it's probably easiest to update over the air, rather than via iTunes. The main fix in iOS 9.0.1 is for an issue that made the [1]Slide to Upgrade screen unresponsive, forcing users to restore their devices in order to perform the update. iOS 9.0.1 also fixes bugs that prevented alarms and timers from playing, caused distorted frames when pausing video in Safari and Photos, and could cause users with custom APNs to lose cellular data. Apple implies that there are security improvements in iOS 9.0.1, but the company's [2]security updates site has yet to be updated with notes for this release. After updating to iOS 9.0.1, your recently updated apps may need to be updated again. If Updates is enabled in Settings > App and iTunes Stores, this will happen automatically.
