Kies mini now on samsung usa site - xda-developers
Saw this on the XDA site, just installed it. Appears now we don't have to download a kies app from the international site. I just finished installing it so I'm not certain how well it works.
For the download, go to the bottom of the page.
Edit: I've now installed it and used it. Didn't do anything the first go around, I'm not sure if this is because of the original usb driver being installed or since i wasn't using touchwiz.
I uninstalled the old usb driver and rebooted the computer. I then tried a usb connected and storage mode worked, but kies did not. I then changed my default usb connection to kies and received a message on the screen saying I needed to be on the "idle" screen and to close my applications. I then changed my launcher back to touchwiz(via home switcher) and then tried it again with kies as default. This worked just fine.
If you were already using kies don't bother with this. It appears Kies mini is strictly for firmware upgrading purposes as it doesn't appear to have any other options. I'd say this gives light to the idea that the 2.2 update will eventually come down through Kies.
