RIM announced that App World is now accepting theme submissions. The announcement was a little buried along with the announcement of the BlackBerry Theme Studio 5, which helps developers make more compelling themes for BlackBerry.
RIM have said that they are taking submissions now, and next month we will see an update to App World with a themes category. Presumably, the category will feature a wide range of themes for all the latest devices including the Storm2.
Stay tuned on BlackBerry Cool for more info.
