+# iOS Jailbreak Detector
+
+
+## Overview
+
+A drop-in class that dynamically detects whether the iOS device your app is running on has been jailbroken or not.
+
+## 100% App Store Submission Safe. No Private API
+
+I myself have a few apps using this class to detect jailbreak devices. So far 100% App Store submission safe.
