I configured an ActiveSync account on a Treo 650 with Versamail 3.5 non SSL. Everything went fine with the sync. I then installed the direct-push update, and after the next sync, the palm went into an endless reboot cycle.

I had to do a hard reset. I did not hotsync, in case there was a conflicting application. I updated to Versamail 3.5, installed the direct-push update, and set up the ActiveSync account again. After the sync, endless reboots again.

Has anyone else experienced this behavior, or have any idea what is going on? I can configure a direct push ActiveSync account to Exchange on this device without issue.
