Anyone know exactly which version of Versamail will work with Verizon's Treo 600? I did some searching, read the P1 FAQs as well as checked out Verizon's website; all without success.

I realize I'll need to pay for it, but it looks like its the only app out there that will sync Outlook inbox subfolders

(PS: I'm posting here because I have the feeling the Versamail version for the Verizon 600 is the same for all 600s... but can someone confirm that?)
