The Kindle Fire's nascent hacking community is heating up, now that Amazon has released the source code for its new Android tablet. Homebrewers, of course, will first have to root the device before tweaking with the Fire's Gingerbread-based build, but fortunately for them, there's already a guide for that. Once that's taken care of, you can also load the Android Market and a slate of other Google apps, using a handy how-to guide published on xda Forums. It certainly doesn't seem like the simplest of processes, but several xda users have posted successful reports. Check out the links below for the full guide, along with the source code download.
