I just read this on another blog
Apple isn’t happy that the US government have been jailbreaking this iPhones.
A spokesperson from Apple told the US Copyright Office that “Current jailbreak technologies now in widespread use utilize unauthorized modifications to the copyrighted bootloader and operating system, resulting in the infringement of the copyrights in those programs”.
In July of last year, the United States government ruled in the favor of iPhone jailbreaks and unlocks as legal, as long as they were not used for piracy purposes. It will be interesting to see if the government take on board Apple’s request.
