I am having the same issue. Had the new Icon with 3.4.6. Received the update to 3.4.7 and had the new icon for a few minutes and then it reverted to the old icon from 3.4.4 on both my desktop and in the app drawer (using ADW launcher EX).
Once I switched to the TW launcher, the new icon reappeared. For me it appears to be an ADW EX issue.
