Cleaning lense

Hi,

I have a Nikon D3100 camera and i have a dot of dust on the inside of the lense. Does anyone know how to clean this, or who could do it for me?

Thanks

Heres a youtube video tutorial,better than me waffling on about it.

Thank you so much for that

Its actually the sensor that i think that has the spec in it :-(

9 times out of 10 I would advise to go back to the Nikon shop but it's a fair trek. So here's a great video from my favourite camera reviewers on YouTube. Digital Rev :)
