Now, Apple has managed to
gain an upper hand over the persistent hackers according to iClarified, thanks to the release
of a new
bootrom, iBoot-359.3.2. The phone firmware, which shipped
on new iPhone 3GSs starting this week, closes previously used doors
A user named "Mathieulh" first noticed
the new bootrom and took a screenshot. It was subsequently
confirmed by Muscle Nerd of the iPhone Dev Team that the loss of the 24kpwn exploit would render the
iPhone unjailbreakable for the time being. This means that the unlocking fixes, such as the utility released by George Hotz, also won't work anymore as they rely on jailbreaking as a preliminary step.
For users wishing
to jailbreak, iPhone jailbreakers are hard at work trying to find
alternative exploits that could be used to unlock the phone.
They suggest, in the meantime, that users purchase older stock of
iPhones or buy refurbished units.
The iPhone 3GS was unlocked
as soon as it was released, thanks to unlockers with iPhone Developer
connections. George Hotz used the iPhone Dev Team's exploit,
along with his own methods, to publish a
route to jailbreaking the phone just weeks later.
