Corporations want to insure that their products are used in a specific way to maximize profits or fulfill contract obligations so they deliberately design the technology to not allow you to, say, register your iPhone with any other company than AT&T in the United States. iPhones made for the European market have no such restrictions and can be registered with any cellular carrier who will take your money and whose technology supports the phone. Americans have cried foul from the get go and there are applications out there that reprogram the firmware of the iPhone to make it possible to register with other carriers, here. These applications also can give an iPhone or other similarly crippled cell phone capabilities it didn't have before so it is now free to do more or you could say it is out of jail. The corporate suits hate this practice and will retaliate if they catch you doing this so it has its risks. Also, jail breaking voids any warranties and may cause your phone or gaming device to fail at some future time. The suits may make sure it fails at some future time.
