I got such an animal working with Nettalk 4.30. I first had this compiled with 4.25 but then it worked perfectly on desktop computers, but not on my PDA.
There is a login-screen, the browses have buttons the usual navigation buttons and also for VIEW record, CHANGE record and SEND an eMail with a PDF attachement.
If you like to test your device send me a PM and then we make an appointment so that you can access my server. If you have Skype running we could chat while testing, would be helpful....
