As promised, the iPhone Dev-Team has released the carrier unlocking tool called Ultrasn0w for US based iPhone 4 users who are stuck with AT&T network. For those of you who don’t know, carrier unlock for US iPhone 4s required complete rewrite of ultrasn0w software because of the new baseband OS present in iPhone 4.
The much awaited all iOS device jailbreak was released earlier today. Dubbed as JailbreakMe 2.0 Star, this tool which runs right under iOS’ Safari browser can jailbreak iPhone 4, 3GS, 3G, iPod touch 3G / 2G and iPad. Once you are done with the jailbreak, you must be wondering what about the unlock? Well, iPhone 3GS and 3G users can unlock their jailbroken devices right now on iOS 4.0.1 / 4.0 on any baseband with existing version of Ultrasn0w. Simply follow the step by step guide posted here to unlock your iPhone so that you can use it with any carrier you like. It is supported on all basebands upto 05.13.04.
Finally! After weeks of hard work, MuscleNerd and PlanetBeing (of Android port for iPhone fame) of the iPhone Dev Team has managed to unlock the new iPhone 4 running on iOS 4. For those of you who don’t know, carrier unlock for US iPhone 4s on AT&T required complete rewrite of ultrasn0w software because of the new baseband OS in iPhone 4.
In an unexpected update to his last blog post titled “Meh”, Geohot has announced that he, for the time being at least has kind of abandoned the whole iPhone jailbreak and unlock scene. The reasons according to him are as follows.
ToolJail has been just updated to version 2.2. This new version brings updates to jailbreak and unlock guides, and links for jailbreak tools for the newly released iOS 4. For those of you who don’t know, ToolJail (like f0recast) is designed to help iPhone newbie’s to 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.
Its here! This is what you all have been waiting for!! Ultrasn0w 0.93 has been released to unlock all iPhones on the latest 05.13.04 (on iOS 4) and 05.12.08 (on 3.1.3) basebands. The guide for unlocking is exactly the same as posted here, except for the Cydia repo which this time is: repo666.ultrasn0w.com. Follow that one until we update the post here! Stay tuned for more!
In a reply to a tweet, MuscleNerd of iPhone Dev Team has confirmed that iOS 4 (formerly iPhone OS 4) is confirmed to be unlockable, and probably so is the yet to be released iPhone 4. What they have actually got this time around is a new exploit for the latest 05.12.01 / 05.13.04 basebands, which they have been saving for months for a major new update - the time for which has now come.
iOS 4 is the first firmware in which Apple has completely cut off the support for aging original iPhone EDGE and iPod touch first-generation. Their decision of course is justified because of the low RAM found in these first-gen devices which were released back in 2007. But all is not lost as the iPhone jailbreak community has now come up with a mod, which brings the complete look and feel of iOS 4 (formerly iPhone OS 4) for iPhone 2G. The mod is basically based on the iPhone OS 3.1.3, to replicate the experience of iOS 4 on iPhone 2G (EDGE).
