Today Tiny Umbrella got an update to save the SHSH Blobs for iOS 4.3.1.
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!
Now Tiny Umbrella supports iPhone 3GS,iPhone 4,iPod 3G,iPod 4,iPad1, and iPad 2. Apple might have closed the SHSH Saving for iOS 4.3. If you haven’t save them so check it out if you are lucky to save them or else save the SHSH Blobs for iOS 4.3.1 and be on the safe side.
You can download tiny Umbrella from here for PC and MAC and be on the safe side.
