A new version of TinyUmbrella, the tool that allows you to take backups of SHSH blobs (ECID SHSH) has just been released to support iOS 4.3.1. TinyUmbrella also protects iPhone 4 from baseband updates.
Apple released iOS 4.3.1 yesterday, which includes improvements and bug fixes.
The backed up SHSH blobs (ECID SHSH) are required if you want to downgrade to previous iOS version as Apple usually stops signing them after a new iOS software update is released.
Semaphore – developer of TinyUmbrella announced the release of the new version on his blog:
TinyUmbrella now supports 4.3.1 for the relevant devices. Currently only iPhone 4 for verizon does not have 4.3.1 support (as there is no 4.3.1 available for the verizon iphone). Enjoy!
You can checkout our step-by-step guide on how to take a backup of SHSH blobs:

- How To Backup SHSH Blobs (ECID SHSH) Using Firmware Umbrella for Windows users
Note: If you have jailbroken your iPhone then Cydia will automatically store the SHSH blobs (ECID SHSH) when you launch it so you don’t need to use TinyUmbrella to take a backup.
As always, let us know how it goes.
