George Francis Hotz is known for being among the group of people who first unlocked the iPhone to work on carriers other than those which Apple officially supported e.g. AT&T. He went to release jailbreaking tools like purplera1n, blackra1n, blacksn0w, a hack the PS3 and recently Limera1n which jailbreaks iOS 4.1.

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 already seen iOS 4.0 Beta 4 (formerly iPhone OS 4) being successfully jailbroken and unlocked on iPhone 3GS and 3G using ultrasn0w and blacksn0w. But for this final release of iOS 4, both the tools are likely going to get an upgrade soon to make them full compatible. The iPhone Dev Team has already promised a full carrier unlocking solution sometime this month for 05.12.01 baseband. Geohot might also update blacksn0w unlock for this latest firmware, which has already been successfully ported to the Beta 4 of iOS 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.

Steve – the guy who was behind PushFix 2.0 (the first real fix for Push Notifications) for unlocked iPhones has just released Blacksn0w RC2. This version of blacksn0w is basically a repackaged version of the original unlock released by geohot, and the fix which was recently released by MSFT Guy for 05.11.07 baseband on iPhone OS 3.1.3.

Yet another update to Sn0wbreeze has been released. This new update version 3.1.3 V1.5.2 brings fix for 64-bit users who were earlier having problems using this software with their iPhone on 64-bit Windows machines. Also added in this version is more speed and reliability, and the package has now been reduced to just 18mb in size. Unfortunately though, Blacksn0w unlock for iPhone 3GS is still crippled in this version, but you can follow the fix posted here for blacksn0w to unlock 05.11.07 baseband on this latest firmware. If you have iPhone 2G, 3G, 3GS or iPhone touch 1G/2G, you can use sn0wbreeze to jailbreak iPhone OS 3.1.3.

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.

If you loved F0recast, you will love this one too. ToolJail is designed for iPhone newbie’s to help them jailbreak and unlock their iPhone and iPod touch. It contains all the necessary jailbreak and unlock instructions, along with how-to’s on DFU and Recovery Mode, downgrading firmware, and direct download links for all the necessary tools required.

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.

Folks behind the Gull1hack tool are also said to be working on a new unlocking tool dubbed Blacksn0w V2 which according to them will ultimately unlock the new iPhone 3.1.3 05.12.01 baseband on iPhone 3GS with new bootrom. I for one wont believe them until they come out with more proof of concept screenshot and videos.

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.

If you accidently updated to the stock iPhone OS 3.1.3 from iTunes and are locked out, you maybe in with a luck as an unlocking tool is said to be out soon. George Hotz has confirmed via his twitter account that he has a working exploit which can unlock the latest 05.12.01 baseband which Apple bundled when they released iPhone 3.1.3 for iPhone and iPod touch earlier this month. While no ETA was given, judging by his tweet, it may not be too long before we get the updated version of blacksn0w which can unlock 05.12.01 baseband on iPhone 3.1.3 firmware.
