Does anybody, anywhere in the world, make a Palm phone that's graffiti-based and supports 850mhz GSM and GPRS data so I can use it with Cingular?

I know that most of the foreign Palm phones can be used with T-Mobile, but I've gotten the impression that T-Mobile's data network utterly sucks and tops out at 19.2k... I'd love to be proven wrong, though...
