MuscleNerd announced an upcoming version of RedSn0w will support restoring and allow for downgrade of the iPhone 4S and iPad 2/3 for those with SHSH Blobs saved.
The iPhone Dev Team have been hard at work implementing additional features and updates to their popular Redsn0w jailbreak tool.
Below you can find links to download RedSn0w, a tool released by the iPhone Dev-Team to jailbreak the iPhone, iPad, and iPod touch.
These are instructions on how to dump the SHSH blobs of your current firmware even if Apple is not signing.
For instance, you can dump the SHSH of the current firmware on your device, so long as the device is susceptible to the Limera1n jailbreak (Everything but the iPad 2) Apple does not have to be signing the SHSH in order for you to dump the blob.
*Note the iPod Touch 2G and iPhone 3G will not work since they will always be jailbreakable. The iPad 2 will not work because it is not susceptible to Limera1n. A jailbreak is not needed for this.

iPhone Dev Team has released Redsn0w 0.9.6r14 to jailbreak iOS 4.3.2 that was released last week for GSM iPhone 4 iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iPad 1 users.
iPhone Dev team has used the untethered iOS 4.3.2 jailbreak developed by iPhone hacking expert Stefan Esser.
Dev Team has provided the following information on their blog:
NOTE: Those of you who rely on a carrier unlock MUST STAY AWAY from Redsn0w and stock iOS 4.3.2 firmware. Also, the patches for 4.3.2 are said to be broken on this version of Redsn0w. PwnageTool 4.3 with 4.3.2 PwnageTool bundles is the recommended.
How to jailbreak iOS 4.3.2 using Redsn0w on Windows and Mac:
Download iOS 4.3.1 (required by Redsn0w 0.9.6 for 4.3.2 jailbreak) for your version of iOS device.
Update/Restore to iOS 4.3.2 firmware using the IPSW file you just downloaded via iTunes 10.2.1.
Start Redsn0w and point it to the official iOS 4.3.1 firmware file (NOT iOS 4.3.2 file).
Create a folder on your desktop called Pwnage
Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 4.3.1 firmware from below and place it in the same folder.
4.3.1 (4 GSM):Download iPhone3,1_4.3.1_8G4_Restore.ipsw
Once iTunes has finished updating your iPhone to the desired firmware open the Pwnage folder on your desktop and launch the redsn0w application from the redsn0w folder we extracted earlier.
Make sure Cydia is selected and click the Next button to continue
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here
Once this is complete you will be notified that RedSn0w is done. Click the Finish button. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.
REMEMBER THAT AFTER YOU DONE JAILBREAKING IT YOUR IDIVICE WILL NOT BOOT IT WILL STAY ON THE APPLE LOGO, SO HERE IS WAHT YOU DO, FOLLOW ALL THE STEPS AGAIN BUT ON STEP 8 DO NOT SELECT CYDIA AGAIN JUST SELECT JUSTBOOT TETHERED RIGHT NOW. AND THAT’S IT BUT EVERY TIME YOU TURN YOUR PHONE OR IPOD OFF YOU WILL HAVE TO DO THAT, TILL A UNTETHERED JAILBREAK IS OUT.
