Yes. Although I don't know what 'CSD' stands for in this context.

The ISP doesn't need special equipment. Your GSM provider (Cingular)
needs modem equipment to convert gsm-data to normal 9600 bps calls.

Your ISP does need to accept calls at those rates. Some have their
modems set up to reject calls at 'lower' speeds.

A Nokia 6620 data cable. A google search for that term gives me,2224,70,00.html

To your computer it will look like a normal modem that understands
Hayes commands to build a connection and dial your ISP. Your phone
will convert it to a gsm-data call. Cingular can have a different rate
for those calls and not count it against 'voice' minutes you may have.

Hope this helps in getting yourself connected,
