Legal iPhone JailBreaking, http://snapvoip.blogspot.com/
I too was very happy to hear the new about the new US Government rules making unlocking and jailbreaking iPhones or any other phone not a crime Even after Apple told them that jailbroken iPhones could crash cell towers ( Apple has told government(PDF) that jailbroken iPhones could crash cell towers). But before dreaming of jailbroken iPhone 4 formed on my mind, I realized that this would only bring a few more developers to the hacking scene. Like the HTC hacker, conflipper, who went through hoops before finally trying to settle with HTC.There might be a few app stores and app market places. I even wonder, there might be some commercial apps and app stores providing banned subjects like porn apps and content, proving the never ending American entrepreneurship. May be now I can get Google Voice running on iPhone :)
"When one jailbreaks a smartphone in order to make the operating system on that phone interoperable with an independently created application that has not been approved by the maker of the smartphone or the maker of its operating system, the modifications that are made purely for the purpose of such interoperability are fair uses."Nothing more, nothing less. There might be openings for banned iPhone Apps but does not Cydia do that already. I might want to pull out that Cydia code and begin hacking, so I can have my own personal store. But all in all, I am happy that this is now an open issue. Also have to thank the Government for not buying Apple bull about blowing up Cell towers.
