avataria hack

avataria hack is a great service that allows you to install and control apps on a rooted device and install additional system apps, but it in addition to allows you to patch APKs to remove ads, generate hacked APK files, emulate levels and premium in-app purchases and thus on. An awesome tool that can be used to create modded / hacked APK files even without a rooted phone. Its my favorite website upon Android in general as it can be used for just about anything including hacking mobile games.
Having a rooted device is not necessary.
