APN wap.cingular (login
WAP@CINGULARGPRS.COM) puts your Treo behind a NAT firewall and routes all traffic through a WAP gateway. This is supported with MediaNET and MediaWORKS plans.
APN isp.cingular (login
ISP@CINGULARGPRS.COM) puts your Treo on a public (though not static) IP address and no WAP gateway. This is supported with a "PDA" or "data" plan -- *not* the same as any Media* package.
APN isp.cingular (login
ISPDA@CINGULARGPRS.COM) is a "data accelerated" option, and works with the same plans as ISP@. It compresses some content (esp web traffic) for "enhanced" performance. Doesn't cost anything extra.

I've seen a wide variety of reports, but I find that isp.cingular is faster than wap.cingular, and I prefer knowing my smartphone isn't using a freakin' WAP gateway. From a truly functional perspective, though, the only applications that I've seen have a problem with wap.cingular are some VPN clients (Mergic is one that I use and doesn't work via WAP... but really this is more a function of what VPN protocols you use to connect, not so much the client itself).
