I would recommend going with the install from the BlackBerry Support website (http://www.blackberry.com/go/softwaredownloads). After unzipping it with WinRAR and comparing it to the one linked on the SmarTone-Vodafone site, I have noted that the one from the BB support site actually does contain the installer for the Media Manager OS, and seems as if it may be more stable. I can't install to test on this PC as there are no admin rights for my username ... however, I encourage someone to try a fresh install of the one hosted on the RIM site and let us know what happens.
