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 4.3.2 and iOS 4.2.7. TinyUmbrella also protects GSM iPhone 4 from baseband updates.
Apple released iOS 4.3.2 and iOS 4.2.7 last week, 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 is now updated to support 4.3.2 / 4.2.7 iOS versions. I’ve also added a simple feature to allow you to ‘Visit Blog’ when updates are available. Enjoy
EDIT: OK so it looks like Cydia is giving up the ghost and having some major issues. I’ve re-uploaded 4.30.05 for those of you that want to save 4.3.1 via APPLE. Hurry up and do so before 4.3.1 is no longer signed.
To save your SHSH via APPLE instead of CYDIA (the default) go into Advanced options and UNCHECK the box that clearly says: “Request SHSH From Cydia” then click ‘Apply Changes’ then select your device then click ‘Save SHSH’

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.
