Steve, the guy who was behind PushFix 2.0 (the first real fix for Push Notifications) for unlocked iPhones and Blacksn0w RC2 fix for iPhone 3.1.3 has just released Blacksn0w RC2 for iOS 4. This version of blacksn0w is basically a repackaged version of the original unlock released by geohot, and the binaries which were recently released by MSFT Guy for 05.11.07 baseband on iPhone 3GS, running iOS 4.0 GM (formerly iPhone OS 4).
We have been hearing about this one aren't we? but what we have now is final confirmation. According to the member of iPhone Dev Team, full carrier unlocks for iPhone OS 3.1.3, and iPhone OS 4.0 will be released this month once Apple has released both the final version of iPhone OS 4, and the next iPhone 4G / HD.
A fix has been released to unlock the latest iPhone 3.1.3 firmware on 05.11.07 baseband using Blacksn0w. Most of you who have tried to unlock iPhone 3.1.3 with 05.11.07 baseband using blacksn0w might have faced this problem where the said tool is unable to unlock iPhone 3G and 3GS. This is because blacksn0w is locating a function to patch by searching the binary for a reference to string "SIM is not supported". In iPhone OS 3.1.3, Apple has replaced the same function in a way that it now uses the string "Verified". Since the location to patch is determined by instruction search&replace, the said patch still works in iPhone 3.1.3 after changing the string and its length in Blacksn0w binary.
Gull1hack and Blacksn0w V2 by the Gull1hack team has now been confirmed as fake by the iPhone Dev-Team. A Release Candidate version of Gull1hack was released the other day which was supposed to jailbreak all iPhone and iPod touch devices on the new bootrom untethered.
A group of hackers are claiming to have found an exploit which will jailbreak iPhone 3GS with new bootrom and it will be untethered. The exploit appears to work not only in iPhone 3GS models with new bootrom, but also in all iPhone and iPod touch models.
