first post, heh... the browser on my pearl is pending connection [couple more hours?]

ok, i downloaded the Desktop Manager v4.3 on my PC, but i cannot access the "application loader" menu because i also need to DL the v4.3 OS to my PC as well, correct? well, i went to the link that the op placed in the thread, but i could not find the v4.3, so what now? i really want to free up some space on my new pearl... thnx guys
