noticed today that an update was available under settings/about phone/system software updates. the new version is 18.104.22.168 and its about a 24mb download. ive always found it quite a nerve racking experience upgrading firmware on mobile phones but everything went very smoothly with a reset at end of upgrade. all settings and saved data still in place. havent found changelog yet but at least vodafone is showing some interest in pushing out firmware updates unlike my previous experiences with o2!!
