Jerry let us know that RIM has updated BlackBerry Traffic in App World to v188.8.131.52. This is a small bugfix update over the previous v184.108.40.2069. This version fixes a bug where guidance stops along with a bug in the BlackBerry calendar integration according to the change log Jerry spotted. Either way if you use BlackBerry Traffic regularly especially with the new voice guidance you may want to update.
