Do you know an exceedingly credible source for the firmware modifications?
(Last time I looked, it had the air of the XDA-style culture: "To root your phone, download this package from a `.ru` piracy site, run the `.exe` on your PC, then install and run the closed blobs on your phone, including rooting and replacing your bootloader with one, we know you will trust us." Though, in their defense, if they were organized crime, they would probably make an effort to look more legitimate, rather than gratuitously suspicious. And all the forum comments were always lapping it up, appearing to be doing reckless things, while removing much of the demand and contributors for more-credible efforts.)
