I'm assuming you mean restoring your data after flashing a new ROM. I would think that it will work the same way, but w/ WMDC, you can't be sure about much
. It took me nearly a year just to be able to sync my 700WX w/Vista. I'm not altogether sure what the issue was, but after I flashed Landon.Epps Full ROM (Verizonized), it went without a hitch. I would suggest using a backup program and/or creating a DashWire account, to be doubly sure that your data will be available.
