Do you mean internet access on your pc from a cell phone?
If so then yes, it's possible with most modern cell phones and with a little reading it seems to be possible with yours. Anyway, what you need is a "data cable"
Nokia sells one for $50 but you can almost certainly do better on ebay.
When I did it with my old Motorola Star-tac it immediately accepted it as a "generic modem" and I only had to set up a dial up connection as usual. I can't say what your case will call for.
The speed was only (I think) 14.4k and was too slow for any useful surfing but it worked. I know some providers offer faster speeds but unless you pay for it you will probably be limited the the 14.4k (I'm making some educated guesses here)
BTW, I used it with my laptop to check email/icq/etc on the road. Pretty cool.
