Now registered Windows Phone developers can receive pre-release OS updates on their dev phone, directly from Microsoft! You can use this app to opt-in your phone to receive early Windows Phone updates before they are generally available, enabling you to run and test your app on real hardware running the latest OS before your customers. 
•         You must meet one of the following three requirements: (a) have an active Windows Phone Dev Center account; (b) have an active App Studio account; OR (c) be running a registered developer device (‘dev unlocked’ phone)
•         Updates will only include the Microsoft update, and not additional OEM drivers/firmware
•         To ensure the best experience, your device must be running the latest OS release (currently 8.0.10322.71) or greater to receive early updates via this program
•         You will be required to accept additional terms & conditions within the app prior to opt-in
•         You CANNOT REVERT to a prior OS version once you have taken an update via this program
Key features:
•         Access to latest pre-release Windows Phone updates
•         Ability to opt-out of pre-releases and only receive production Windows Phone updates

    I was tired of waiting for AT&T to release Denim for the Lumia 1020, so I'm glad I could install the updates via this app. A couple of problems though: 1. Some apps don't recognize the preview release as an official version of Windows Phone software, so you cannot install them. This poses problems if you need to update an app to use it, like the MLB At Bat app. 2. I'm also experiencing a strange anomaly where the OS thinks I do not have an app installed, shortly after phone update automatically runs an update check. Specifically, this is an issue for me with the Twitter app. The app icon remains on the home screen but is grayed out, and if I tap on it, I'm prompted to install the app from the store.
