I've Installed the 8530 Version on my T-Mobile UK 8520 and after a very slow download, and it works well despite having to put a fake North American Cell Number in. I've now relegated Vodafone Update to a backup app as Social Beat is far more polished and suited to my screen size than VU. Social Beat has got to be my new favourite Social Networking app. Facebook for BlackBerry and Twitter for BlackBerry have been relegated to backups for when I need a fuller featured app for uploading pictures to fb and Twitter.
