do you recomend blue tooth on mobile

I think that I'm out of date when it comes to mobile phones! Up until a week ago I still had one of those old fashioned nokia phones. Then things changed! I recently purchased a Samsung U6oo mobile phone and I have to say, it looks really nice! It has video as well as photo capability and it also has bluetooth! I haven't used this facility as yet but I'm thinking that it is very convenient. If you have a friend who also has bluetooth on their mobile then you can transfer files and photos wirelessly when you are within range of them. I guess I'm finally catching up with the times now when it comes to mobile phones! Andrew
