uses DFU mode to try to automatically determine which device and FW you have
fetches pieces of public IPSWs from Apple (once). Non-public IPSWs must be provided manually (once). It then caches those pieces for future use.
“Just boot” is a tethered boot. Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
“Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
“Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails). Should work on iOS5 beta too
“Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
“SHSH blobs” has a bunch of options…
“Fetch” – fetch current PARTIAL blobs on device. Should complete in under 10 or 15 seconds. Puts the set of PARTIAL of blobs on your computer as a plist. Checks if Cydia already has a full set for this device and build. If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
“Verify” – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server. You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
“Submit” – both verifies and submits one or more blob files to Cydia. This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
“Query” - queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
“Stitch” – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW
Stitching is NOT yet supported on iPhones! Need to work out the baseband part of the restore process.
FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes. No need to start TU or use Cydia though.
Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores. No need to start TU or use Cydia though./li>
Will eventually support fetching the blobs directly from Cydia instead of a file on your computer
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, iPhone 4, iPad, iPad 2, iPod Touch and even future iPhone 4S and iPhone 5.
MuscleNerd, hacker from DevTeam, has announced via Twitter that a major update to RedSn0w is coming soon.
There will be no need to select an IPSW. Rather than requiring ipsw selection, RedSn0w will now automatically fetch the important pieces directly from Apple (and caches them so that it never needs to re-fetch them again). New version also brings the ability to save and submit SHSH Blobs to Cydia.
Will be pushing out a major redsn0w feature upgrade before my trip to Korea: http://is.gd/PMAdT1 (and look, no IPSW selection button!)
The new version of RedSn0w is expected to be released on Monday.
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.
iH8Sn0w released Sn0wBreeze 2.8b7, which adds jailbreak support for the latest iOS 5 beta 7 firmware.
Sn0wBreeze creates custom firmware and allows users to preserve baseband for unlock (ultrasn0w doesn’t work with iOS 5 yet). This new version also adds hacktivation and removes UDID developer check. This means that you can try iOS 5 without developer account from Apple.
You can download Sn0wBreeze 2.8b7 for Windows here.

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.
Here is a nice video overview of popular Cydia apps.
My personal top 30 Cydia tweaks of 2011. The tweaks chosen are both new and old, popular and unpopular. 30 is a big number so, I hope that most of you are able to find a tweak that you will enjoy having on your iPhone, iPod Touch, or iPad. The tweaks are my personal picks and we all will have our opinion. I know that there are allot of other awesome Cydia tweaks that I was unable to mention but, feel free to tell us about them in a video response or comment.
The founder of Jailbreakme.comComex has said on Twitter that he is joining Apple as an intern. Site JailbreakMe.com greatly facilitates jailbreaking for users. He said about the hiring on Twitter:
“It’s been really, really fun, but it’s also been a while and I’ve been getting bored. So, the week after next I will be starting an internship with Apple”.
