Finally, copy the com.amazon.cloud9-1.apk from the /data/app directory to /system/app. Reboot your device, and you should be ready to rock with the Silk browser.

So, how well does Silk work on a hacked Android device? We ran performance tests with a Nexus S running Silk, not running Silk, and then running Silk with Amazon's AWS Accelerated Page Loading, but the results were not impressive. The Nexus S served pages like in about 7 seconds on the standard browser and an average of 6 with Silk; however, it took an average of about 9 seconds to deliver the same page when we turned on Accelerated Page Loading. The larger or more content-intensive the site, the slower the loading. In our tests on the rooted Nexus S, we saw no discernible performance difference using the Silk browser on Wi-Fi, as opposed to 3G, either.

If that seems odd, bear in mind that Amazon has claimed that the cloud caching service must operate for a while in order to learn (and thus anticipate) popular browsing habits. Ideally the app should become speedier over time as it figures out what content to load first. That means more people need to start using Silk as their primary browser--so if you have a rooted Android device, this hack should provide an opportunity to put the Silk browser through its paces. Good luck!
