It looks like Apple is upping its game in an attempt to stop the iPhone being jailbroken, iPhone Dev Team member MuscleNerd has confirmed that Apple are shipping the iPhone 3GS with a bootrom update, iBoot-359.3.2 which will stop the iPhone 3Gs being jailbroken for the moment.
The bootrom update is resistant to the 24kpwn exploit that is used by the Dev Team and other jailbreakers to jailbreak the iPhone.
I am sure it won’t be long before we see a solution from either the iPhone Dev Team or from George Hotz, who recently brought us the Blackra1n iPhone jailbreak.
