It sounds cruel, but the iPhone Dev Team has a sound reason for not jumping the gun. “We can jailbreak the 3GS right now,” it reveals, but “once the jailbreak is out, Apple will fix the iBoot-family bug we use to accomplish it. If you bought your phone after Apple has done this, there’s nothing you can do…the jailbreak isn’t going to work for you.”
This relies on Apple updating the iPhone OS 3.0 software in the near future, which is quite likely once the various bugs are identified. Apple also needs to fix the previous Ultrasn0w exploit too, ironically. The iPhone Dev Team admits that Apple could still find out how to prevent the unreleased iPhone 3GS hack by itself, but doesn’t want to hand it over on a silver platter.
So you’ll have to stay patient in the meantime, and once iPhone OS 3.0.1 is launched, the iPhone 3GS will be hacked open like a ripe watermelon.
