Versamail vs Wireless Sync

I'm up to my eyeballs in frustration over syncing. My Palm Treo 755p will not sync my Palm Desktop calendar or contacts. All else will sync. Maddening. Now I do suspect it has something to do with also having wireless sync. The only reason I have wireless sync is: one day my phone completely crashed.......wiped everything out and I was out showing property (there went my supra key and phone numbers). I had to get to my computer to get everything back. Well, what if I'm travelling and this happens? Wireless sync at least would put me back in business. Dick, I recall in your class you said something about staying away form wireless sync. I need to know what to do and how to do it!

Thanks, Ann
