(politely saying) read above posts. Metro pcs phones stock or rooted. It's a 3g boost. Some say it helped 2g some say it decreased 2g. Speeds. I suggest you try it. It's an easy process. U can always switch back if it decrease your speed. Run speed test before u change it then run speed test afterwards. Then you will know which is better for you.
