What is difference between mfacebook and facebook?

I am not all to sure myself. I just know a couple things. If your Computer is old and www.Facebook is giving you problems, then use m.Facebook! My computer has problems with www.Facebook but has NO problems with m.Facebook. M.Facebook is simpler and MUCH faster! If you have an older computer try m.Facebook, and your problems will likely go away. I highly recommend m.Facebook - especially if your computer is older. M may stand for Mobile but It also stands for Magic solution to computer website problems. m.Myspace works on my Computer but www.Myspace does NOT work at all! I have problems with www.Twitter but m.Twitter works great and is much faster! If you are having problems with site that start in WWW try starting with M!
