Closed exploit a minor obstacle
Jailbreaking indeed remains an option for the iPhone 3GS, says a member of the unofficial iPhone Dev Team. "It's not going to be impossible to jailbreak even if the exploit we used is gone," notes Eric McDonald, responding to some media reports claiming that 3GS jailbreaks might be impossible with the closure of the 24kpwn exploit. Apple has begun shipping 3GS units with a new bootrom, rendering the hole ineffective.
In reality, says McDonald, the only difficulty caused by Apple's change relates to starting up an iPhone. If a new jailbroken 3GS runs out of power or is otherwise shutdown, it cannot be restarted without connecting it to a computer via USB. The same problem is said to have occurred with the second-generation iPod touch, only to be resolved in a relatively short space of time. It is unknown if modern Touches are also being given a bootrom update.
