What do you use your mobile phone for ? Can you do without your mobil phone and why? What other digital do you find the most important for you ? Напишите письмо

First of all, I use my mobile phone for calls. Also Im chatting with my friends using the phone and of course surfing the Net. I cant do anything without my phone, because now its the integral part of my life. I always carry it in my pocket. I can find everything I need in Internet using the phone, I can call someone in case of need. As for me the other important digital is MP3-player. I like listen to music and I cant live without it. I listen to music everywhere. It has an ability to cheer up and so I think its very important.
