For your Android, BlackBerry, iPhone or Windows Phone 7 you can download Wikitude from the respective markets (Android Market, BlackBerry AppWorld, AppStore or Marketplace). For Symbian devices, you can usually download it from Nokia Store. However, as Ovi Store is currently facing some technical difficulties, we are also offering Wikitude for Symbian on our webpage.
