SOURCE: Cydiahelp
The iPhone Dev Team today released a major update, Redsn0w 0.9.9b1, which they’ve promised to release with so many major improvements and features. Redsn0w 0.9.9b1 is now available for download with many major improvement and features. Below, we’ve made a quick walk-through inside the Redsnow 0.9.9b1 version.


Once you start Redsn0w 0.9.9b1, you get a totally new screen asks you to choose either “Jailbreak” or “Extras”. Once you get to Extras, you’ve a lot of options to do.

First of all, Redsn0w 0.9.9b1 extras include the Just Boot option which is made for those tethered-jailbroken devices. Tethered means you have to connect your device to your computer every time it reboots and choose Just Boot option from Redsn0w so it opens again.
Second option in Redsn0w 0.9.9b1: Pwned DFU, this option is made for those restoring via iTunes using custom IPSW firmwares cooked by Sn0wbreeze or PwnageTool. Putting your device in Pwned DFU mode will bypass so many errors that would appear without it.
Recovery fix is the next option. It’s the same as many apps as Recboot and TinyUmbrella which allows you to get kick your device out of Recovery mode (or enter it) which may be caused by iTunes errors while restoring.
The most important option is that SHSH Blobs, it includes many options inside it. Here’s the options:

• Fetch - fetch current partial blobs on your iOS device.  Should complete in under 10 or 15 seconds.  Puts the set 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.

Redsn0w 0.9.9b1 also includes an option called Select IPSW which is for picking non-public IPSWs, or overriding auto-detection.
Need more clarification? Well, we’ve made a quick guide to jailbreak iOS 5 beta 7 using Redsn0w 0.9.9b1:

STEP 3: Now you’ll have to follow the on-screen instructions to enter the DFU mode.
