Caches version 2.2 for iOS

This morning saw a version 2.2 of the Caches app released from the App Store. The "What New…" section of the app stores lists;

• …fixes a bug where the compass may not respond to heading changes.
• Additionally, you can now open caches and waypoints in third-party navigation apps. Supported apps are Apple Maps, GoogleMaps, Navigon and TomTom. And I’ve fixed some minor bugs.

The app is $3.99 in the App Store for new users and free for upgrading users.
