Been using this freeware program for a while, and it works very well for exactly what you are describing:

The freeware doesn't "translate" files like activesync does (say, for example, it won't reflow .pdf documents). They do, however, offer an add-on non-freeware program that will translate files. I haven't tried this program and can't offer an opinion.
