This issue was briefly touched on in
this thread, but I thought I would start a new thread to discuss it, as it may not be firmware update related. My Treo loses connection to Vision at least a couple of times a day. The only way to reestablish a Vision connection is to either power cycle the radio, or to perform a soft reset. This renders apps like Snappermail and QuickNews less effective, as they're unable to update automatically.
I'm curious how many others are having this issue, and on what firmware version?
