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 love having the ability to update my HTC 8x to reveal the new features released through this program. I've had a couple sim card problems, to where it would go unrecognized until I restart my phone. Also when "change photo" is pressed when trying to change lock screen, freezes and crashes to the start screen multiple times before I get lucky and it goes through to my photos. Other then that I'm digging Cortana and the live folders!
