I spend 2 days to get this going after reading all kinds of Forum, how you should do this and do that, nothing works at all. I down loaded the samsung kies from uk version 1.5 and it work only for media and SD. also try to download PDAnet and still crap, none of this work at all because it does not reconize the driver. I have a Lenovo T410 labtop and a Tmobile Galaxy S SGH-T959. was tired of running around so I came accross this one down load. come to find out that the phone version was a 2.1, all you have to do is down load this driver to update your phone version to 2.2
