i730 as a modem

I know there was an earlier thread about Nextel phones as modems. Was there
any definite resolutions? I wish to use my i730 as a modem for my HP PDA.
I have the necessary cable.

I'm aware Nextel has a Dial Up program of $10/month. Why couldn't I just
use cell minutes? Do I need software in my i730?

Thx!!

you need a data plan to get up to 56k or use the s=2 option to use at 19.2k
