No you can't.

No digital phone has a real "modem" in it- just a way totransfer data
to/from a cell carrier. The carrier then uses a "real" modem at their
HQ for you, to connect you to the outside world.

Unfortunately, AT&T doesn't have a bank of modems at HQ for this
purpose, so they don't support data transfer over TDMA. Cingular
does, so your phone's "modem" would work if you were a Cingular TDMA
customer.

It's not a connection problem, just a carrier who doesn't support TDMA
CSD (Circuit Switch Data) calls.

Analog mode would be useless- the "modem" in your phone only works in
digital mode, with a compatible carrier. In analog mode you'd need a
special interface cable to connect the phone to a real analog modem,
which were available a few years ago for a few popular phones (Nokia
5160, for example) for big bucks.

The special interface cables generally forced the phones into analog
mode.
