Just hours after the iPhone 2.0 operating system went live on Apple's servers, it was revealed to have been jailbroken for quite some time, with the iPhone Dev Team set to release its Pwnage tool in the coming weeks. Gizmodo reveals it has been using the jailbroken iPhone 2.0 for its Push email test coverage, with the unreleased Pwnage tool having been available privately for the last couple of weeks, since build version 5A345.
The utility of Pwnage has somewhat decreased due to the iPhone being available the world over, and the contract requirement at purchase, but is still useful for those who wish to run unsigned applications or alternate SIM cards while traveling.
