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

    After the last update my phone is very unstable, very slow, the camera has very poor quality. When i bought this phone one year ago everything was very good, very smooth, the camera had very good quality, noe, i cannot photograph one page because i cannot read the letters, one year ago, i was photographing 3 pages pf a document at once and it had very good quality. I dont need vortana or extra gestures. I need a well working device first of all.

    Was working great, but since the latest update (today is 11/15/14) my Lumia 920 has been crashing/rebooting several times day. Hope you find the bugs and fix on next update? Love the Cortana!
