UPDATED: Samsung PC Suite (updated version 7.7.2.20.9) is available to download from http://uk.samsungmobile.com/supports/softwaremanuals/software.do?phone_model=GT-I8510&sw_type=SW
Note: If the installer fails or seems to be taking a long time (more than 5 minutes without doing anything) then uninstall ALL Samsung PC Suite components, including the CDMA drivers; then restart your computer and re-run the new installer.
