With the release of iPhone OS 4.3.4, Apple has not only corrected the exploit used by Comex in JailbreakMe, but has also laid permanently correct the security flaw in iOS identified by i0n1c 4.3 and later versions. Unfortunately the bad news for users interested in the jailbreak does not end here: Apple has also corrected the exploit to jailbreak that hackers used untethered from the days of firmware 4.1.
To give the news via Twitter was I0n1c, which states:
For those who have not understood, iPhone OS 4.3.4 fails to correct only JailbreakMe 3.0 as announced, but it crashes (silently) also ndrv_setspec () integer overflow.
In addition to this, the code also adds iPhone OS 4.3.4 can detect binaries that use a "code signing incomplete). This type of codes have been used for some time, since firmware 4.1.
We remember so that the jailbreak for iPhone OS 4.3.x untethered distributed and executable programs such as Redsn0w, PwnageTool and Sn0wbreeze is no longer usable.
Given the upcoming release of iPhone OS 5, it seems very unlikely that the development team of the jailbreak can use their strengths to find new exploits to be distributed specifically to iPhone OS 4.3.4. Therefore, if you're interested in the jailbreak, the general advice is to stay away from the new firmware.
