Samsung Kies 2.0 Released
Used for syncing and updating various Samsung phones, the Samsung Kies software for PC has been updated to version 220.127.116.1111_16_5. Although a auto check from my existing version 1.5.3 did not return a new update notification, you can download the new version directly from Samsung support site.
The new version has a smaller installation file size, redesigned layout and interface compare to version 1.5.3. Detail change log is not available at the moment.
