The firmware intended for running native third-party software on the iPhone has already been jailbroken, a well-known hacking group claims. The iPhone Dev Team says that after less than a day with the SDK's bundled v1.2 firmware, to eventually be renamed v2.0 for June launch, it was able to decrypt the disk image and run applications without a developer's certificate. Downloaders of the SDK must technically be a part of iPhone Developer Program, which costs $99 for most parties.
The Dev Team notes however that even if the firmware were publicly released today, the hack would not be of any use to people on an official iPhone contract with AT&T. The new jailbreaking technique requires a hacked activation, meaning that users would have to have a "virgin" iPhone, whether newly bought or somehow restored after the fact.
