Apple releases iOS 7.1.2; update exterminates bugs and improves iBeacon
The update to iOS 7.1.2 will also bring some connectivity improvements and added stability to iBeacon. This is the connectivity tool that uses Bluetooth LE to send directed messages to iDevices based on location. For example, at the Apple Store, iBeacon can send a coupon for accessories to iPhone users standing in the accessories department of the store. Those looking at iPads could receive a coupon for one of Apple's tablets.
Apple started working on iOS 7.1.2 at around the time it released iOS 7.1.1. Apple's carrier partners just received the new build last week. The update is being sent out via an OTA update. If you're the impatient type, you can try to coax the update out of your device by using the software update tool in the Settings app on your iOS flavored device.
