With ChevronWP7 closing down
, the homebrew community for code on modern devices faced a significant challenge. Either you had an older device, like the original Samsung Focus, that had custom ROM's available for interop or full unlock, or you paid the $99 fee for a full AppHub account (unless you were lucky enough to own a ChevronWP7 unlock token already, and got free AppHub access). Thanks to the ingenuity of the programmers at XDA, the barriers for some newer phones have been knocked down.
First off, we covered what the different unlocks were back when highlighting the screenshot app
, but let's have a quick refresher:

Think of it like this: dev unlock is to XNA as interop unlock is to OpenZDK. The latter allows much more powerful programs to be written outside of the normal framework provided.
For an even better in-depth look, the author of WP7 Root Tools has written this guide
since then, so go check that out if you're interested in running one of these unlocks. Now that we have the basics covered, what exactly has been done here?
There are a few unlocks available, courtesy of biktor_gj on XDA's forums. First came an interop unlock for both the Lumia 800 and 710. Then a full unlock was released for the 800, with another full unlock on the way for the 710 (on is currently available but incomplete and not recommended for regular use). You need a full unlock to properly run WP7 Root Tools and really make the most of your unlocks. Currently these unlocks are not available for everyone; they only function under one bootloader, which can be tested for in a procedure outlined in the release topic. It is of course recommended that a full backup of the phone is taken before making any such alterations to it, as it may not work and will necessarily wipe your phone in the process of installing the ROM. No mention is made of the Lumia 900, and despite the phone's similarity to the 800 when dealing with such low-level operations there are going to be differences so don't go trying to run it on your shiny new 900 until an official release is made. Basically, be safe and have fun with your newfound freedom!
