Saw today in the booklet with Dirge and Blurr, the advertisment for the WFC game has the Ramjet unlock code for the Decepticon DS - 9871. Looking online, it is either that or 99871 (an extra 9 at the front).
I also found that the Silverbolt unlock for the Autobot DS game is 10141.

Too late to be news, so figured I could just post it here.
