D Conference creators AllThingsD today unveiled a new conference specifically tailored to mobile with both conspicuous additions and omissions, including Apple. The D: Dive Into Mobile event will be held in San Francisco on December 6 and 7 and will include a relatively rare appearance by Palm chief Jon Rubinstein, who has been mostly silent since a takeover by HP. Other highlights should include RIM co-CEO Mike Lazaridis, Microsoft Windows Phone lead Joe Belfiore. Both Google's Android and ad VPs, Andy Rubin and Susan Wojcicki, should be present.
