The iPhone Dev-Team has just updated the ultrasn0w unlocking tool for iPhone 4, 3GS and 3G. This new version has lots of new tweaks added for performance and stability improvement. It will also help with standby battery life incase if your phone is draining the battery too fast. The compatibility though remains the same. It will work with all iPhones up to iOS 4.0.1 with baseband 04.26.08, 05.11.07, 05.12.01 and 05.13.04.

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.

The iPhone Dev-Team Members MuscleNerd and Planetbeing has confirmed that even though the unlock for iPhone 4 with ultrasn0w is ready and all, they will still do thorough testing in the next 48 hours to make sure everything is working before it is released to public. This is what they said on their respective Twitter accounts

Here is a quick update on the upcoming Comex’s jailbreak for iPhone 4 and iOS 4 / 4.0.1. It was only yesterday when we informed you all that Comex in an interview said that he is “almost” done with the jailbreak and now he is waiting for Saurik (the creator of Cydia) to complete the last bits which are required for the jailbreak.

Listening to an all-star podcast interview which involved iPhone devs like Comex, Planetbeing, Chpwn and iH8sn0w who are working on jailbreak and unlock scene, there was this question which the hosts asked the devs about when is the iPhone 4 and iOS 4.x jailbreak is expected to be out. While no specific release date was given, they did said that jailbreak is “pretty close to done”. They are now waiting for Saurik (creator of Cydia) to fix couple of loose ends before it is released. iPhone 4 unlock on the other hand is 100 percent done and is waiting for jailbreak to be released.

PwnageTool bundle to jailbreak iOS 4.0.1 on iPhone 3GS has been released. You can use this bundle with existing version of PwnageTool to create custom firmware files which are jailbroken and hacktivated for iPhone 3GS. The best thing about this bundle is that it supports both the ultrasn0w unlock and hacktivation. But as always, this bundle is meant for iPhone 3GS with old bootrom only. Those of you who are with new bootrom will have to wait for Comex’s new Spirit like jailbreak tool which should be released real soon.

iOS 4.0.1 was released earlier today for iPhone 4, 3GS and 3G. Fortunately for all iPhone unlockers, the baseband wasn’t upgraded from 05.13.04, which means you can unlock your iPhone even on the latest iOS 4.0.1 firmware. Since currently there is no jailbreak tool available for iPhone 4 and iPhone 3GS (new bootrom), and the current jailbreak tools for iPhone 3GS (old bootrom) are not compatible with iOS 4.0.1, so the only device which can currently be jailbroken and unlocked on iOS 4.0.1 is iPhone 3G.

iOS 4.0.1 has just been released by Apple for iPhone 4, iPhone 3GS and iPhone 3G to fix the reception issues which has been problematic for most iPhone 4 users since its launch last month. iPhone 3GS and iPhone 3G users who currently rely on an unlock MUST STAY from iOS 4.0.1 until any further notice. Updating to iOS 4.1 might result in update of baseband, which will potentially lock your phone. You wont be able to unlock it until a new exploit is found again.

The most vocal of all iPhone Dev Team members – MuscleNerd today updated on the whole iPhone 4 unlock situation which he has been working on with @planetbeing (of Android port for iPhone fame). For those of you who don’t know, carrier unlock for US iPhone 4s on AT&T requires complete rewrite of ultrasn0w software because of the new baseband OS in iPhone 4.
