i just got a samsung i500 phone. It seems that the drivers don't "hold" after a restart or after I shut down my computer. I am not sure if another program is disabling the drivers or if the drivers need to be updated. Once i uninstall/reinstall, things work fine until i start my computer the next day. I have win xp sp1 as an os. I have searched the samsund/sprintPCS support sites but have not found any relevant information.
