The iPhone Dev-Team has released a new and improved version of redsn0w, its popular jailbreak tool. Now, users of the software can take advantage of a variety of exciting features, including the ability to kick an iOS device out of recovery mode, and support for those all-important SHSH blobs.

As outlined by the iPhone Dev-Team itself, new features added in redsn0w 0.9.9b1 (which is available for both Windows and Mac), include:

  • 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

Previously, in order to have all the above features on-board, jailbreak fans would have to have downloaded a variety of separate applications (such as PwnageTool and TinyUmbrella). Now, it’s possible to do so much more from within one single application, which is great.

The iPhone Dev-Team notes that the software still supports the same iOS firmware as before, and that this update only adds the above features.
