Trading from a PDA?

Has anyone here traded from a PDA (Blackberry or Treo etc.) with Interactive Brokers?

I just want to know about your experience and which PDA you used, your network plan, etc.

Thanks

 

This was via Cybertrader, and I had to call them to get a link that worked. It turned out to me a little different than the one Cybetrader provided. I have data service on me treo, so I can hook a laptop up to it using PDANet and use the standard app, or just access the link via the PDA browser

 

I see that IB offers a PDA platform

 

And where will you get R/T charts?
IB's are not good for DT.
