When do you use mobile phones

I use a mobile phone on a daily bases i do not leave the house with out mine, it is how i comunicate with my friends and arrange to meet up. I also use mine as a camera and a music player, because it saves carrying around an ipod, camera and phone when you can have them all in one. The only problem with mobile phones is that it messes up your english becasue you speak in text messaging language rather then normal english for example before would be 'b4' and tonight would be '2nite'. i think that a mobile phone fulfils its purpose and above.
