Please help!

I have recently purchased an Ipaq 5550, and also have a bluetooth phone. I know how to link the phone and Ipaq together (read the HP guides etc).

My question is can you use your mobile to dial up, say, your normal Freeserve connection on the normal number (the one you use for your home computer) and then use the same username and password as on your home computer or is it more complicated than that?

Thanks in advance for anybody who can help. If a specialist ISP provider is required can somebody advise as to who is best?
