Daniel Bigham has been on a roll with PlayBook apps. His latest is iTunes sync which synchronizes your iTunes music collection to your PlayBook with the latest music you have purchased. RIM offers a way to do this with a wired Desktop Manager connection but now you can do it over Wi-Fi. Daniel created iTunes Sync based on the demand you all showed in the article he wrote on BerryReview previously.
Right now the app will bring your iTunes music to your PlayBook when you click the sync button but it won’t sync the other way around. You can pick it up in App World here.
