Because external SD mount point has changed in unofficial ICS builds (CM9), I've developed a small app which binds /emmc to /sdcard/external_sd as it was in Gingerbread.
Designed for Samsung smartphones with internal and external SD such as Galaxy S and Galaxy Note series. Works on rooted devices only.
* CM10 compatible
* bug fixes
* enhanced compatibility with Android 4.1+ by adding more "original mount point" options
* hopefully fixed service loop and battery drain issue reported by some users
* added EXPERIMENTAL fix for broken Usb Mass Storage
* bugfixes and minor code improvements
* Forced MEDIA SCANNER for new mount point
* Removed mount/unmount delay options. Delay is now automatic.
