It contains a slew of applications in /xbin that were previously not available. I also added busybox (type "adb shell busybox" to see what commands are available).
Apps2SD is also set to go for you guys.
All you have to do is create an ext2 partition on your sd card (browse the dream forum to learn how to do this) then type:
adb shell cp -r /data/app /system/sd/app adb shell cp -r /data/app-private /system/sd/app-private adb shell rm -r /data/app adb shell ln -s /system/sd/app /data/app adb shell rm - /data/app-private adb shell ln -s /system/sd/app-private /data/app-private
