Free your phone, once again. Successfully tested on Gingerbread
(2.3.3) but might also run on Froyo and Honeycomb. If it fails
there, some offsets and indexes need to be adjusted which is
left to the reader.

failure or damage. Make sure to read the README file carefully!

[This software is >1 year old meanwhile, most vendors fixed
the bug already. So its unlikely to run on new devices.]
[Update] I replaced the tarball with a new version to fix
some glitches while parsing vold.fstab. Should now also
work on the GalaxyS. Thx to Chainfire.
