I had a unlocked iPhone 3G right before I got my iPhone 4 a couple of days ago. I remember making calls on my new phone and seeing the facetime button on the screen but now after syncing my iPhone 4 up with my old 3G backup the hold button is now in the place of the facetime button. I've tried going into my settings and looking for a facetime toggle switch but its not there. Is there any solution to this besides restoring as a new device?
