The free Galaxy_S Unlock (Market/XDA link) app is confirmed to SIM unlock the Galaxy S2 (SC-02C). The app description indicates that it does not work with "older Docomo phones," so it is unlikely to work with the original Docomo Galaxy S (SC-02B). It also doesn't seem to yet work with the S3. The app requires root access, as well.
It creates a backup, but it goes without saying that this is a bit dangerous, so use it at your own risk.
The app's developer helroz is relatively new to XDA Developers but seems to be doing good work and garnering respect. The internet permissions on the app is for downloading a generic unlocked nv_data file to use to build a real unlocked nv_data file.
hi if i root my sc-02c, can i unlock it via this app?? its
