May force new workarounds
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.
Devices equipped with the new bootrom should thus be harder to hack even with the latest utilities, namely PwnageTool 3.1.4 and blackra1n. It is suggested that people still interested in hacking a 3GS should for the time being only buy from older stock, such as refurbished models. It may still be possible to jailbreak a 3GS through alternate means, while tethered to a computer.
