Notes about autorom: Right now it is only for 16gb sdcard this will change soon, but it will resize the sdcard so if you dont have a 16gb sdcard you can either do it manually or edit the setup_2 file and remove the line the that has /system/xbin/mk16gbsdpart.sh and then it will not do the sdcard and it will just load the rom.
