If you are lucky enough to live in one of the countries where the Samsung Galaxy SII has been released, then you might be thrilled about this news. The new super-phone already has a root method and a custom ROM from some sharp hackers over at XDA Developers. The custom ROM is called VillianROM 1.0. Here's a quote from the AndroidCentral article,
The maker does note that he sent the VillainROM 1.0 software to another forum member and it was able to unlock the phone and worked as expected. As with any custom software, you individual mileage may vary and what works for one S II might not work for them all. Be sure you can fix your device before you try to use the software. To use VillainROM 1.0 requires the use of ODIN and the ROM is flashed as a PDA image.

The author notes you donít check anything else for the install other than PDA, and there are apparently other options so be sure you pick the correct one. The ROM is based on XWKE2 and has tweaks installed to allow for future mods to the ROM . The author also notes that people applying this update should not try to use Villain Tweaks or problems will ensue.
If any of our "international" forum members are able to give this a try, please sound off in the forums to let us know what you think.
