Is there a way to assign an application that you have transferred to an SD card to a button e.g. Sprint Business Connection Email client on a SD card to the email button on the Treo650? I am not happy with Versa Mail at all since it does not synch deletions even though I have specifies in my preferences that it should delete mail from my POP3 server when I delete it from my T650. Sprint BC is a lot more robust.
