So you only want to back up SMS, email, contacts, and calendar it sounds like. I use an Exchange server so I've never had a problem with switching between WinMo devices or restoring after a hard reset. I also have never cared to backup sms so that doesn't bother me either. I doubt my situation really helps you.

I would suggest searching for pim backup, or sms backup, or contacts backup. Worst case cenario - you may just have to use several pieces of software to transfer your sms, another for your email, ect.
