Before I flashed 2.17 I used the dirvers to get my 6Gb Sandisk to work... Ran with them for a while and had no issues with them. If I remember right... You need to give them a min. after installing them, then turn off your phone for a min. or so, and when you restart your phone it will work... IT WILL NOT WORK IF YOU INSTALL AND RESTART WITH OUT GIVING IT TIME TO SAVE
