Jailbreak iPhone, iPod Touch, iPad

The iPhone Dev-Team has released RedSn0w 0.9.8b7b to bring two new main features:

• explicit tethered jailbreak support for iOS 5 Beta 7
• untethered jailbreak for iPhone 3GS with old bootrom (iOS 4.3.5 or iOS 5 Beta 7)

Musclenerd posted via twitter:

New redsn0w is.gd/6eek4Y explicitly supports iOS5b7 (no need to point at b6 IPSW). Also brings back old-bootrom 3GS goodies.

This is great news for both developers and owners of old bootrom iPhone 3GS’s who accidentally updated to iOS 4.3.5.

DevTeam posted:

About 12 hours after we released redsn0w 0.9.8b7 with some improvements for iOS5b6, Apple went and released iOS5b7 (what are the odds of that?!?). Even though that redsn0w could still jailbreak iOS5b7, you needed to point it at the iOS5b6 IPSW to do so. Today’s redsn0w 0.9.8b7b lets you point redsn0w directly at the iOS5b7 IPSW instead.

We’ve also added some overall improvements for old-bootrom 3GS owners (where the 24kpwn exploit applies): on those devices, you can tell redsn0w to untether 4.3.5 and lower, or iOS5b7. Old-bootrom 3GS owners can once again choose custom logos, and/or verbose booting (for the really nerdy iPhone3GS fans out there!). And it allows 4.3.4 or 4.3.5 users to use ultrasn0w again (if they have a compatible baseband).

Last but not least, we fixed some lingering Verizon iPhone4 4.2.10 JB issues.

We will update our tutorials shortly.

You can download RedSn0w 0.9.8b7b here.

Here are links to our RedSn0w 0.9.8b7b iOS 4.3.5 jailbreak tutorials:

• Windows: iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G, iPod Touch 4G

Currently iOS 4.2.1 jailbreak for iPhone 4, iPhone 3GS new bootrom, iPad, iPod 3G/4G is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again. Musclenerd from iPhone DevTeam has announced that untethered jailbreak for iPhone iOS 4.2.1 is ready. Unfortunately this will be only for those who saved 4.2b3 SHSH keys via Cydia or tinyumbrella.

Got “backup plan” for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you.

“Backup plan” because hacker comex is working on a more extensible jailbreak. We’ll keep you up to date with more information as it develops. For now you can watch the proof video:

A few hours ago iH8sn0w posted a tweet that he is able to run jailbreak on the new firmware 4.0 beta 1. DarkMalloc, another developer who worked on the project, has just released new video that shows firmware 4.0 jailbreak on iPhone 3G:

The interesting thing, besides the presence of Cydia and MobileTerminal, is the possibility to have multiple applications open at once. That means that multitasking on iPhone 3G can be enabled. Officially Apple doesn’t want to activate this functionality on iPhone 3G, just iPhone 3GS and later devices.
