if you have dial up, click here and sign up. once signed up you wont need to use the free uk dial up. you can just set outlook/outlook express up to check the freeuk account (this keeps the account active)
You will need dial up to install this because you need to download the setup file. (if you only have BB as i do, you can give it a go and see if it will allow you to set up the account manually) but as far as i can remember you need to dial into the account once to activate it.
