fee for IPAQ-cell net use?

I am probably worrying way to much about accessories for for the IPAQ I don't have yet. But... I want to connect a 3835 IPAQ to my samsung SCH-8500 cell with sprint. I found this cable:<br>http://www.socketcom.com/product/dpc_sam.htm#<br>I think it sould work, But do I need to pay for the extra monthly fee for Web Enabled Phone service to use it for the IPAQ?<br>Some people on Amazon said it didnt work, maybe because of that. ( http://www.amazon.com/exec/obidos/tg/st ... 95-7711737 )<br><br>........My God, I have way too much time on my hands... I did like a hour of research on an accessory for an item I dont yet have!... Better than staring at a blank wall though.
