A minor revision of the iPhone 3GS is now shipping with a new bootrom, preventing the use of somecurrent jailbreaking techniques, hackers claim. Phones with iBoot 359.3.2 are believed to have gone on sale last week, quietly and without explanation from Apple. The new code is said to prevent the 24kpwn exploit, however, which has been used for some time in jailbreaking tools, including those from the unofficial iPhone Dev Team.
