yeah you can but i recomend system toolbox...it does the same thing but it has a more user friendly interface. the most useful things about it is that you can remove system apps really easily because not only does it have the apk file name but it also shows the app icons which makes it really easy to find the ones you want to remove. You can boot into recovery mode, there is extra system tweaks, better gps server. I assume that you are rooted?
