Strictly speaking, cookies are not part of the WAP 1.1 specification, and it
is currently very rare for a WAP device to support them. However, many
gateways (most notably the UP.Link, which is what I use) can store cookies
on behalf of devices. The main reason for the cookies not to exist on a WAP
device is that they are costly (in terms of processing power and memory) to
implement.
One possible alternative is to implement the hidden field functionality of
HTML.
Cheers!
