T-Zones Pro on Treo ??

I badly want to access T-Zones Pro on my Treo 600 so that I can have access to my email (which runs on an Exchange server).

For those who don't know, using T-Zones Pro (which I originally configured for my Nokia 6250) it is possible to get "native" access to an exchange server. That is, you have direct access to your inbox, contacts and schedule. It isn't Pop3. You can see all of your inbox, if you delete a message it goes to your "deleted" file in the exchange server, and if you send a message it sends a copy to your "sent messages" box. More importantly, it doesn't require any cooperation from our IT department.

Now, having bored everyone with a long explanation, can it be done? T-Mobile support has tried to help. They say it is a wap application tied to voicestream.com. The Blazer browser doesn't support WAP so I got jBrowser. But I can't figure out how to configure it (even though T-Zones now appears, without my intervention, as one of the "connection" options in jBrowser).
