Semi-Tethered jailbreak iOS 5:
The iPhone Dev-Team has released an update to their UltraSn0w unlock bringing support for iOS 5. Remember that NO new basebands are supported in this release. It only adds support for iOS 5 with old basebands.
Here is the list of supported basebands:
If have one of the above baseband version and need unlock you can upgrade to iOS 5 without updating your baseband using .
Ultrasn0w 1.2.4 is available in Cydia.

UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.
If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:
For iPhone 3G the latest is iOS 4.2.1. You can perform jailbreak with any utility. For iOS 4.2.1 you can also use them or GreenPois0n (Windows, Mac OS).
iPad 2 jailbreak is available only for iOS 4.3.3 via JailbreakMe and and iOS 5.0.1 via Absenthe.
iPhone 4S jailbreak is available for iOS 5.0 / iOS 5.0.1 via Absenthe.
Apple stopped signing iOS 4.3.3, so you cannot update to iOS 4.3.3 without SHSH keys saved (in advance some time ago). If you have , iPhone 3GS, iPad 1, iPod Touch 3G or iPod Touch 4G that run iOS 4.3.3 – use JailbreakMe or RedSn0w to untether jailbreak your device.
If you have saved SHSH keys for iOS 4.3.3 you can use PwnageTool (Mac OS) or Sn0wBreeze (Windows).
For iOS 4.3.4/4.3.5 only tethered jailbreak is possible with redsn0w. Tethered means that each time you restart your device you will have to connect it to a computer and run redsn0w. The untethered iOS 4.3.5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using .
To jailbreak and unlock iOS 5 use latest version of redsn0w 0.9.9 or sn0wbreeze 2.8. You can jailbreak tethered or .

MuscleNerd has announced via Twitter that jailbreak utility RedSn0w 0.9.9b1 is released with major update and numerous new features:
Major improvements and features added to redsn0w 0.9.9b1! See update #9 at http://is.gd/6eek4Y Feedback: @redsn0w_testers
Indeed the list of new features is quite high. There are two main ones:
However this new version does not bring features like untethered jailbreak for iOS 4.3.5 or iOS 5.
Due to some possible bugs we still recommend to use the old RedSn0w 0.9.8b7b, but the new 0.9.9b1 is worth seeing and playing with.
Here are links to our RedSn0w 0.9.8b7b iOS 4.3.5 jailbreak tutorials:

Here is the full list of features from DevTeam:

Hackers from the Chronic Dev Team recently announced that they have found 5 userland exploits in iOS 5. To us this means that it is very likely that an untethered jailbreak will be available for the upcoming firmware release.
P0sixninja made the announcement at MyGreatFest jailbreak conference held in London, England.
While this is a “record breaking number of exploits found”, userland exploits can be easily fixed via a minor software update. The exploits are kept in secret, so hopefully Apple won’t fix them before the expected iOS 5 launch next month.
The jailbreak is expected for all devices, including iPhone 3GS, , iPad, iPad 2, iPod Touch and even future iPhone 4S and iPhone 5.
The iPhone Dev-Team has released RedSn0w 0.9.8b7b to bring two new main features:
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 4.2.10 JB issues.
We will update our tutorials shortly.

The iPhone Dev-Team recently released RedSn0w 0.9.8b7 which brings explicit support for a tethered 4.3.5 jailbreak as well as new iOS 5.0b6 iPad 1 jailbreak:
Apple updated the iPad1 iOS5b6 IPSW without changing its version number or filename, so we’re releasing redsn0w 0.9.8b7 to handle both the original and changed IPSW. We’ve also added explicit support for a tethered 4.3.5/4.2.10 jailbreak (instead of pointing at the 4.3.4/4.2.9 IPSWs) and fixed a 4.2.10 problem.
You can download RedSn0w 0.9.8b7 .

RedSn0w can perform a tethered jailbreak on iOS 4.3.5 for all devices except the iPad 2, according to MuscleNerd’s tweet:
So those who really do want tethered 4.3.5 can use redsn0w pointed at 4.3.4 (except iPad2)
We strongly recommend NOT to update to iOS 4.3.4 or iOS 4.3.5 to preserve untethered jailbreak. We will soon post step-by-step tutorials on how to perform iOS 4.3.5 tethered jailbreak.

The iPhone Dev-Team has released RedSn0w 0.9.8b3 which can perform a tethered jailbreak on iOS 4.3.4. This means that you will have to connect your device to a computer and run redsn0w each time you restart.
For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2. The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is! There are no new features in 4.3.4 – only fixes for jailbreak exploits.
Also, this is a good time to remind everyone (since we’re still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed. This is unlike every other device, so don’t be confused! iPad2 owners with basebands should stay away from all updates to maintain your jailbreak!
This jailbreak works with iPhone 3GS, , iPad 1, iPod Touch 3G and iPod Touch 4G. It does not work with iPad 2.

Famous iPhone hacker Stefan Esser, also known as i0n1c, recently wrote on twitter that we should not expect untether jailbreak for iOS 4.3.4 anytime soon. i0n1c was the one who created untether for iOS 4.3.3 firmware.
Our advice is simple – save your 4.3.3 SHSH keys asap. With these SHSH keys you will be able to restore to iOS 4.3.3 anytime, without – only iOS 4.3.4. Here are tutorials for you.
