MuscleNerd is one of the most prominent members of the jailbreak community, and his vast knowledge has helped the iPhone Dev Team continue to update and improve its Redsn0w utility in the progressive cat and mouse battle. Apart from jailbreaking, MuscleNerd and other Dev Team members continue to dabble in the unlocking game as well, and with the Cupertino's sought-after device mostly sold subsidized - i.e. locked under a contractual agreement with a carrier - there are plenty of iPhone users on the lookout for an unlock.
Unless their chipset has already been exploited and jailbroken on a previous device, it takes a lot of time for the iOS jailbreaking community to come with a jailbreak for a new iOS device. The iPhone 4S and iPad 2, both of which are based on a still (bootrom) unexploited dual-core A5 chip, haven’t received a jailbreak for iOS 5 yet, but it appears that they’ll be getting one soon as a certain eminent iPhone hacker has let us know that the iPhone 4S has already been jailbroken with a jailbreak for iPad 2 in the works.
If you've been following the news for the last few hours, you're probably aware that the latest build of iOS 5, known as "Beta 4", was seeded to developers. This is also the first ever version of iOS that can be downloaded over-the-air to iOS 5 Beta 3 devices, removing the need for iTunes to apply this update altogether. It now turns out that if you've jailbroken iOS 5, you won't be able to update over the air.
According to a tweet posted by @MuscleNerd, a member of the iPhone Dev-Team, which has authored many jailbreak-related tools and tutorials, iOS 5's new automatic over-the-air updates shouldn't make jailbreaking harder.
The iPhone Dev Team today has released an updated version of Ultrasn0w unlock to fix signal bar issues on iOS 4.3.1 compatible iPhones, running on the old baseband.
The just released PwnageTool 4.3 can jailbreak iOS 4.3.1 on iPhone 4, 3GS, iPad (1st-gen), iPod touch 4G/3G, Apple TV, and at the same time will help retain the old baseband for iPhone 4 and 3GS users so that they can unlock using the existing version of Ultrasn0w.
Two interesting little jailbreak tidbits to come out of hacker MuscleNerd's Twitter account today with news of an untethered 4.3.1 jailbreak as well as his thoughts on rumors of a spy in the jailbreak camp.
After demoing his untethered jailbreak on iOS 4.3.1, iPhone security expert and hacker Stefan Esser has confirmed that he has now handed over the exploit to the members of the iPhone Dev-Team and that it is currently in internal beta testing stage.
The iPhone Dev Team has confirmed that a Windows version of Redsn0w 0.9.7 is on its way for jailbreaking iOS 4.2.1 with iOS 4.1 IPSW instead of iOS 4.2b3 firmware and SHSH blobs.
The iPhone Dev Team has released yet another update to Redsn0w 0.9.7 jailbreak tool. This new version fixes all sandbox-related issues, including Bluetooth problems on an untethered iOS 4.2.1 jailbreak. Also added is an “anti-piracy plea” note as a warning for those of you who are pirating iOS 4.2 beta 3 firmware.
